 please consider we favor
 [asynchronous communication](https://about.gitlab.com/handbook/communication/#internal-communication) over real time communication. Thanks for your contribution!
 
-## Workflow labels
-
-To allow for asynchronous issue handling, we use [milestones][milestones-page]
-and [labels][labels-page]. Leads and product managers handle most of the
-scheduling into milestones. Labelling is a task for everyone.
-
-Most issues will have labels for at least one of the following:
+## Contribution Flow
 
-- Type: ~"feature proposal", ~bug, ~customer, etc.
-- Subject: ~wiki, ~"container registry", ~ldap, ~api, ~frontend, etc.
-- Team: ~"CI/CD", ~Plan, ~Manage, ~Quality, etc.
-- Release Scoping: ~Deliverable, ~Stretch, ~"Next Patch Release"
-- Priority: ~P1, ~P2, ~P3, ~P4
-- Severity: ~S1, ~S2, ~S3, ~S4
+When contributing to GitLab, your merge request is subject to review by merge request maintainers of a particular specialty.
 
-All labels, their meaning and priority are defined on the
-[labels page][labels-page].
+When you submit code to GitLab, we really want it to get merged, but there will be times when it will not be merged.
 
-If you come across an issue that has none of these, and you're allowed to set
-labels, you can _always_ add the team and type, and often also the subject.
+When maintainers are reading through a merge request they may request guidance from other maintainers. If merge request maintainers conclude that the code should not be merged, our reasons will be fully disclosed. If it has been decided that the code quality is not up to GitLab’s standards, the merge request maintainer will refer the author to our docs and code style guides, and provide some guidance.
 
-[milestones-page]: https://gitlab.com/gitlab-org/gitlab-ce/milestones
-[labels-page]: https://gitlab.com/gitlab-org/gitlab-ce/labels
+Sometimes style guides will be followed but the code will lack structural integrity, or the maintainer will have reservations about the code’s overall quality. When there is a reservation the maintainer will inform the author and provide some guidance.  The author may then choose to update the merge request. Once the merge request has been updated and reassigned to the maintainer, they will review the code again. Once the code has been resubmitted any number of times, the maintainer may choose to close the merge request with a summary of why it will not be merged, as well as some guidance. If the merge request is closed the maintainer will be open to discussion as to how to improve the code so it can be approved in the future.
 
-### Type labels
+GitLab will do its best to review community contributions as quickly as possible. Specially appointed developers review community contributions daily. You may take a look at the [team page](https://about.gitlab.com/team/) for the merge request coach who specializes in the type of code you have written and mention them in the merge request.  For example, if you have written some JavaScript in your code then you should mention the frontend merge request coach. If your code has multiple disciplines you may mention multiple merge request coaches.
 
-Type labels are very important. They define what kind of issue this is. Every
-issue should have one or more.
+GitLab receives a lot of community contributions, so if your code has not been reviewed within 4 days of its initial submission feel free to re-mention the appropriate merge request coach.
 
-Examples of type labels are ~"feature proposal", ~bug, ~customer, ~security,
-and ~"direction".
+When submitting code to GitLab, you may feel that your contribution requires the aid of an external library. If your code includes an external library please provide a link to the library, as well as reasons for including it.
 
-A number of type labels have a priority assigned to them, which automatically
-makes them float to the top, depending on their importance.
+When your code contains more than 500 changes, any major breaking changes, or an external library, `@mention` a maintainer in the merge request. If you are not sure who to mention, the reviewer will add one early in the merge request process.
 
-Type labels are always lowercase, and can have any color, besides blue (which is
-already reserved for subject labels).

-The descriptions on the [labels page][labels-page] explain what falls under each type label.
 
-### Subject labels
+## Workflow labels
 
-Subject labels are labels that define what area or feature of GitLab this issue
-hits. They are not always necessary, but very convenient.
+This [documentation](doc/development/contributing/issue_workflow.md) has been moved.  
 
-Examples of subject labels are ~wiki, ~ldap, ~api,
-~issues, ~"merge requests", ~labels, and ~"container registry".
 
-If you are an expert in a particular area, it makes it easier to find issues to
-work on. You can also subscribe to those labels to receive an email each time an
-issue is labeled with a subject label corresponding to your expertise.
+### Type labels
 
-Subject labels are always all-lowercase.
+This [documentation](doc/development/contributing/issue_workflow.md) has been moved.
 
-### Team labels
 
-Team labels specify what team is responsible for this issue.
-Assigning a team label makes sure issues get the attention of the appropriate
-people.
+### Subject labels
 
-The current team labels are:
+This [documentation](doc/development/contributing/issue_workflow.md) has been moved.
 
-- ~Configuration
-- ~"CI/CD"
-- ~Create
-- ~Distribution
-- ~Documentation
-- ~Geo
-- ~Gitaly
-- ~Manage
-- ~Monitoring
-- ~Plan
-- ~Quality
-- ~Release
-- ~Secure
-- ~UX
 
-The descriptions on the [labels page][labels-page] explain what falls under the
-responsibility of each team.
+### Team labels
 
-Within those team labels, we also have the ~backend and ~frontend labels to
-indicate if an issue needs backend work, frontend work, or both.
+This [documentation](doc/development/contributing/issue_workflow.md) has been moved.
 
-Team labels are always capitalized so that they show up as the first label for
-any issue.
 
 ### Release Scoping labels
 
-Release Scoping labels help us clearly communicate expectations of the work for the
-release. There are three levels of Release Scoping labels:
-
-- ~Deliverable: Issues that are expected to be delivered in the current
-  milestone.
-- ~Stretch: Issues that are a stretch goal for delivering in the current
-  milestone. If these issues are not done in the current release, they will
-  strongly be considered for the next release.
-- ~"Next Patch Release": Issues to put in the next patch release. Work on these
-  first, and add the "Pick Into X" label to the merge request, along with the
-  appropriate milestone.
+This [documentation](doc/development/contributing/issue_workflow.md) has been moved.
 
-Each issue scheduled for the current milestone should be labeled ~Deliverable
-or ~"Stretch". Any open issue for a previous milestone should be labeled
-~"Next Patch Release", or otherwise rescheduled to a different milestone.
 
 ### Priority labels
 
-Priority labels help us define the time a ~bug fix should be completed. Priority determines how quickly the defect turnaround time must be.
-If there are multiple defects, the priority decides which defect has to be fixed immediately versus later.
-This label documents the planned timeline & urgency which is used to measure against our actual SLA on delivering ~bug fixes.
+This [documentation](doc/development/contributing/issue_workflow.md) has been moved.
 
-| Label | Meaning         | Estimate time to fix                                             |
-|-------|-----------------|------------------------------------------------------------------|
-| ~P1   | Urgent Priority | The current release + potentially immediate hotfix to GitLab.com |
-| ~P2   | High Priority   | The next release                                                 |
-| ~P3   | Medium Priority | Within the next 3 releases (approx one quarter)                  |
-| ~P4   | Low Priority    | Anything outside the next 3 releases (approx beyond one quarter) |
 
 ### Severity labels
 
-Severity labels help us clearly communicate the impact of a ~bug on users.
-
-| Label | Meaning           | Impact on Functionality                               | Example |
-|-------|-------------------|-------------------------------------------------------|---------|
-| ~S1   | Blocker           | Outage, broken feature with no workaround             | Unable to create an issue. Data corruption/loss. Security breach. |
-| ~S2   | Critical Severity | Broken Feature, workaround too complex & unacceptable | Can push commits, but only via the command line. |
-| ~S3   | Major Severity    | Broken Feature, workaround acceptable                 | Can create merge requests only from the Merge Requests page, not through the Issue. |
-| ~S4   | Low Severity      | Functionality inconvenience or cosmetic issue         | Label colors are incorrect / not being displayed. |
+This [documentation](doc/development/contributing/issue_workflow.md) has been moved.
 
 #### Severity impact guidance
 
-Severity levels can be applied further depending on the facet of the impact; e.g. Affected customers, GitLab.com availability, performance and etc. The below is a guideline.
+This [documentation](doc/development/contributing/issue_workflow.md) has been moved.
 
-| Severity | Affected Customers/Users                                            | GitLab.com Availability                            |  Performance Degradation     |
-|----------|---------------------------------------------------------------------|----------------------------------------------------|------------------------------|
-| ~S1      | >50% users affected (possible company extinction level event)       | Significant impact on all of GitLab.com            |                              |
-| ~S2      | Many users or multiple paid customers affected (but not apocalyptic)| Significant impact on large portions of GitLab.com | Degradation is guaranteed to occur in the near future |
-| ~S3      | A few users or a single paid customer affected                      | Limited impact on important portions of GitLab.com | Degradation is likely to occur in the near future     |
-| ~S4      | No paid users/customer affected, or expected to in the near future  | Minor impact on on GitLab.com                      | Degradation _may_ occur but it's not likely           |
 
 ### Label for community contributors
 
-Issues that are beneficial to our users, 'nice to haves', that we currently do
-not have the capacity for or want to give the priority to, are labeled as
-~"Accepting Merge Requests", so the community can make a contribution.
-
-Community contributors can submit merge requests for any issue they want, but
-the ~"Accepting Merge Requests" label has a special meaning. It points to
-changes that:
-
-1. We already agreed on,
-1. Are well-defined,
-1. Are likely to get accepted by a maintainer.
-
-We want to avoid a situation when a contributor picks an
-~"Accepting Merge Requests" issue and then their merge request gets closed,
-because we realize that it does not fit our vision, or we want to solve it in a
-different way.
-
-We add the ~"Accepting Merge Requests" label to:
-
-- Low priority ~bug issues (i.e. we do not add it to the bugs that we want to
-solve in the ~"Next Patch Release")
-- Small ~"feature proposal"
-- Small ~"technical debt" issues
+This [documentation](doc/development/contributing/issue_workflow.md) has been moved.
 
-After adding the ~"Accepting Merge Requests" label, we try to estimate the
-[weight](#issue-weight) of the issue. We use issue weight to let contributors
-know how difficult the issue is. Additionally:
-
-- We advertise ["Accepting Merge Requests" issues with weight < 5][up-for-grabs]
-  as suitable for people that have never contributed to GitLab before on the
-  [Up For Grabs campaign](http://up-for-grabs.net)
-- We encourage people that have never contributed to any open source project to
-  look for ["Accepting Merge Requests" issues with a weight of 1][firt-timers]
-
-If you've decided that you would like to work on an issue, please @-mention
-the [appropriate product manager](https://about.gitlab.com/handbook/product/#who-to-talk-to-for-what)
-as soon as possible. The product manager will then pull in appropriate GitLab team
-members to further discuss scope, design, and technical considerations. This will
-ensure that that your contribution is aligned with the GitLab product and minimize
-any rework and delay in getting it merged into master.
-
-GitLab team members who apply the ~"Accepting Merge Requests" label to an issue
-should update the issue description with a responsible product manager, inviting
-any potential community contributor to @-mention per above.
-
-[up-for-grabs]: https://gitlab.com/gitlab-org/gitlab-ce/issues?label_name=Accepting+Merge+Requests&scope=all&sort=weight_asc&state=opened

 ## Implement design & UI elements
 
-For guidance on UX implementation at GitLab, please refer to our [Design System](https://design.gitlab.com/).
-
-The UX team uses labels to manage their workflow.
-
-The  ~"UX" label on an issue is a signal to the UX team that it will need UX attention.
-To better understand the priority by which UX tackles issues, see the [UX section](https://about.gitlab.com/handbook/engineering/ux) of the handbook.
-
-Once an issue has been worked on and is ready for development, a UXer removes the ~"UX" label and applies the ~"UX ready" label to that issue.
+This [documentation](doc/development/contributing/design.md) has been moved.
 
-The UX team has a special type label called ~"design artifact". This label indicates that the final output
-for an issue is a UX solution/design. The solution will be developed by frontend and/or backend in a subsequent milestone.
-Any issue labeled ~"design artifact" should not also be labeled ~"frontend" or ~"backend" since no development is
-needed until the solution has been decided.
-
-~"design artifact" issues are like any other issue and should contain a milestone label, ~"Deliverable" or ~"Stretch", when scheduled in the current milestone.
-
-To prevent the misunderstanding that a feature will be be delivered in the
-assigned milestone, when only UX design is planned for that milestone, the
-Product Manager should create a separate issue for the ~"design artifact",
-assign the ~UX, ~"design artifact" and ~"Deliverable" labels, add a milestone
-and use a title that makes it clear that the scheduled issue is design only
-(e.g. `Design exploration for XYZ`).
-
-When the ~"design artifact" issue has been completed, the UXer removes the ~UX
-label, adds the ~"UX ready" label and closes the issue. This indicates the
-design artifact is complete. The UXer will also copy the designs to related
-issues for implementation in an upcoming milestone.
 
 ## Issue tracker
 
-To get support for your particular problem please use the
-[getting help channels](https://about.gitlab.com/getting-help/).
-
-The [GitLab CE issue tracker on GitLab.com][ce-tracker] is for bugs concerning
-the latest GitLab release and [feature proposals](#feature-proposals).
-
-When submitting an issue please conform to the issue submission guidelines
-listed below. Not all issues will be addressed and your issue is more likely to
-be addressed if you submit a merge request which partially or fully solves
-the issue.
-
-If you're unsure where to post, post to the [mailing list][google-group] or
-[Stack Overflow][stackoverflow] first. There are a lot of helpful GitLab users
-there who may be able to help you quickly. If your particular issue turns out
-to be a bug, it will find its way from there.
-
-If it happens that you know the solution to an existing bug, please first
-open the issue in order to keep track of it and then open the relevant merge
-request that potentially fixes it.
+This [documentation](doc/development/contributing/issue_workflow.md) has been moved.
 
 ### Issue triaging
 
-Our issue triage policies are [described in our handbook]. You are very welcome
-to help the GitLab team triage issues. We also organize [issue bash events] once
-every quarter.
-
-The most important thing is making sure valid issues receive feedback from the
-development team. Therefore the priority is mentioning developers that can help
-on those issues. Please select someone with relevant experience from the
-[GitLab team][team]. If there is nobody mentioned with that expertise look in
-the commit history for the affected files to find someone.
+This [documentation](doc/development/contributing/issue_workflow.md) has been moved.
 
-We also use [GitLab Triage] to automate some triaging policies. This is
-currently setup as a [scheduled pipeline] running on [quality/triage-ops]
-project.
-
-[described in our handbook]: https://about.gitlab.com/handbook/engineering/issue-triage/
-[issue bash events]: https://gitlab.com/gitlab-org/gitlab-ce/issues/17815
-[GitLab Triage]: https://gitlab.com/gitlab-org/gitlab-triage
-[scheduled pipeline]: https://gitlab.com/gitlab-org/quality/triage-ops/pipeline_schedules/10512/edit
-[quality/triage-ops]: https://gitlab.com/gitlab-org/quality/triage-ops
 
 ### Feature proposals
 
-To create a feature proposal for CE, open an issue on the
-[issue tracker of CE][ce-tracker].
-
-For feature proposals for EE, open an issue on the
-[issue tracker of EE][ee-tracker].
-
-In order to help track the feature proposals, we have created a
-[`feature proposal`][fpl] label. For the time being, users that are not members
-of the project cannot add labels. You can instead ask one of the [core team]
-members to add the label ~"feature proposal" to the issue or add the following
-code snippet right after your description in a new line: `~"feature proposal"`.
-
-Please keep feature proposals as small and simple as possible, complex ones
-might be edited to make them small and simple.
-
-Please submit Feature Proposals using the ['Feature Proposal' issue template](.gitlab/issue_templates/Feature Proposal.md) provided on the issue tracker.
-
-For changes in the interface, it is helpful to include a mockup. Issues that add to, or change, the interface should
-be given the ~"UX" label. This will allow the UX team to provide input and guidance. You may
-need to ask one of the [core team] members to add the label, if you do not have permissions to do it by yourself.
-
-If you want to create something yourself, consider opening an issue first to
-discuss whether it is interesting to include this in GitLab.
+This [documentation](doc/development/contributing/issue_workflow.md) has been moved.
 
 ### Issue tracker guidelines
 
-**[Search the issue tracker][ce-tracker]** for similar entries before
-submitting your own, there's a good chance somebody else had the same issue or
-feature proposal. Show your support with an award emoji and/or join the
-discussion.
+This [documentation](doc/development/contributing/issue_workflow.md) has been moved.
 
-Please submit bugs using the ['Bug' issue template](.gitlab/issue_templates/Bug.md) provided on the issue tracker.
-The text in the parenthesis is there to help you with what to include. Omit it
-when submitting the actual issue. You can copy-paste it and then edit as you
-see fit.
 
 ### Issue weight
 
-Issue weight allows us to get an idea of the amount of work required to solve
-one or multiple issues. This makes it possible to schedule work more accurately.
-
-You are encouraged to set the weight of any issue. Following the guidelines
-below will make it easy to manage this, without unnecessary overhead.
-
-1. Set weight for any issue at the earliest possible convenience
-1. If you don't agree with a set weight, discuss with other developers until
-consensus is reached about the weight
-1. Issue weights are an abstract measurement of complexity of the issue. Do not
-relate issue weight directly to time. This is called [anchoring](https://en.wikipedia.org/wiki/Anchoring)
-and something you want to avoid.
-1. Something that has a weight of 1 (or no weight) is really small and simple.
-Something that is 9 is rewriting a large fundamental part of GitLab,
-which might lead to many hard problems to solve. Changing some text in GitLab
-is probably 1, adding a new Git Hook maybe 4 or 5, big features 7-9.
-1. If something is very large, it should probably be split up in multiple
-issues or chunks. You can simply not set the weight of a parent issue and set
-weights to children issues.
-
-### Regression issues
+This [documentation](doc/development/contributing/issue_workflow.md) has been moved.
 
-Every monthly release has a corresponding issue on the CE issue tracker to keep
-track of functionality broken by that release and any fixes that need to be
-included in a patch release (see [8.3 Regressions] as an example).
 
-As outlined in the issue description, the intended workflow is to post one note
-with a reference to an issue describing the regression, and then to update that
-note with a reference to the merge request that fixes it as it becomes available.

-If you're a contributor who doesn't have the required permissions to update
-other users' notes, please post a new note with a reference to both the issue
-and the merge request.
+### Regression issues
 
-The release manager will [update the notes] in the regression issue as fixes are
-addressed.
+This [documentation](doc/development/contributing/issue_workflow.md) has been moved.
 
-[8.3 Regressions]: https://gitlab.com/gitlab-org/gitlab-ce/issues/4127
-[update the notes]: https://gitlab.com/gitlab-org/release-tools/blob/master/doc/pro-tips.md#update-the-regression-issue
 
 ### Technical and UX debt
 
-In order to track things that can be improved in GitLab's codebase,
-we use the ~"technical debt" label in [GitLab's issue tracker][ce-tracker].
-For user experience improvements, we use the ~"UX debt" label.
-
-These labels should be added to issues that describe things that can be improved,
-shortcuts that have been taken, features that need additional attention, and all
-other things that have been left behind due to high velocity of development.
-For example, code that needs refactoring should use the ~"technical debt" label,
-user experience refinements should use the ~"UX debt" label.
+This [documentation](doc/development/contributing/issue_workflow.md) has been moved.
 
-Everyone can create an issue, though you may need to ask for adding a specific
-label, if you do not have permissions to do it by yourself. Additional labels
-can be combined with these labels, to make it easier to schedule
-the improvements for a release.
-
-Issues tagged with these labels have the same priority like issues
-that describe a new feature to be introduced in GitLab, and should be scheduled
-for a release by the appropriate person.
-
-Make sure to mention the merge request that the ~"technical debt" issue or
-~"UX debt" issue is associated with in the description of the issue.
 
 ### Stewardship
 
-For issues related to the open source stewardship of GitLab,
-there is the ~"stewardship" label.
-
-This label is to be used for issues in which the stewardship of GitLab
-is a topic of discussion. For instance if GitLab Inc. is planning to add
-features from GitLab EE to GitLab CE, related issues would be labelled with
-~"stewardship".
-
-A recent example of this was the issue for
-[bringing the time tracking API to GitLab CE][time-tracking-issue].
+This [documentation](doc/development/contributing/issue_workflow.md) has been moved.
 
-[time-tracking-issue]: https://gitlab.com/gitlab-org/gitlab-ce/issues/25517#note_20019084
 
 ## Merge requests
 
-We welcome merge requests with fixes and improvements to GitLab code, tests,
-and/or documentation. The issues that are specifically suitable for
-community contributions are listed with the label
-[`Accepting Merge Requests` on our issue tracker for CE][accepting-mrs-ce]
-and [EE][accepting-mrs-ee], but you are free to contribute to any other issue
-you want.
-
-Please note that if an issue is marked for the current milestone either before
-or while you are working on it, a team member may take over the merge request
-in order to ensure the work is finished before the release date.
-
-If you want to add a new feature that is not labeled it is best to first create
-a feedback issue (if there isn't one already) and leave a comment asking for it
-to be marked as `Accepting Merge Requests`. Please include screenshots or
-wireframes if the feature will also change the UI.
-
-Merge requests should be opened at [GitLab.com][gitlab-mr-tracker].
+This [documentation](doc/development/contributing/merge_request_workflow.md) has been moved.
 
-If you are new to GitLab development (or web development in general), see the
-[I want to contribute!](#i-want-to-contribute) section to get you started with
-some potentially easy issues.
-
-To start with GitLab development download the [GitLab Development Kit][gdk] and
-see the [Development section](doc/development/README.md) for some guidelines.
 
 ### Merge request guidelines
 
-If you can, please submit a merge request with the fix or improvements
-including tests. If you don't know how to fix the issue but can write a test
-that exposes the issue we will accept that as well. In general bug fixes that
-include a regression test are merged quickly while new features without proper
-tests are least likely to receive timely feedback. The workflow to make a merge
-request is as follows:
-
-1. Fork the project into your personal space on GitLab.com
-1. Create a feature branch, branch away from `master`
-1. Write [tests](https://docs.gitlab.com/ee/development/rake_tasks.html#run-tests) and code
-1. [Generate a changelog entry with `bin/changelog`][changelog]
-1. If you are writing documentation, make sure to follow the
-   [documentation guidelines][doc-guidelines]
-1. If you have multiple commits please combine them into a few logically
-  organized commits by [squashing them][git-squash]
-1. Push the commit(s) to your fork
-1. Submit a merge request (MR) to the `master` branch
-  1. Your merge request needs at least 1 approval but feel free to require more.
-    For instance if you're touching backend and frontend code, it's a good idea
-    to require 2 approvals: 1 from a backend maintainer and 1 from a frontend
-    maintainer
-  1. You don't have to select any approvers, but you can if you really want
-    specific people to approve your merge request
-1. The MR title should describe the change you want to make
-1. The MR description should give a motive for your change and the method you
-   used to achieve it.
-  1. If you are contributing code, fill in the template already provided in the
-     "Description" field.
-  1. If you are contributing documentation, choose `Documentation` from the
-     "Choose a template" menu and fill in the template.
-  1. Mention the issue(s) your merge request solves, using the `Solves #XXX` or
-    `Closes #XXX` syntax to auto-close the issue(s) once the merge request will
-    be merged.
-1. If you're allowed to, set a relevant milestone and labels
-1. If the MR changes the UI it should include *Before* and *After* screenshots
-1. If the MR changes CSS classes please include the list of affected pages,
-   `grep css-class ./app -R`
-1. Be prepared to answer questions and incorporate feedback even if requests
-   for this arrive weeks or months after your MR submission
-  1. If a discussion has been addressed, select the "Resolve discussion" button
-    beneath it to mark it resolved.
-1. If your MR touches code that executes shell commands, reads or opens files or
-   handles paths to files on disk, make sure it adheres to the
-   [shell command guidelines](doc/development/shell_commands.md)
-1. If your code creates new files on disk please read the
-   [shared files guidelines](doc/development/shared_files.md).
-1. When writing commit messages please follow
-   [these](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html)
-   [guidelines](http://chris.beams.io/posts/git-commit/).
-1. If your merge request adds one or more migrations, make sure to execute all
-   migrations on a fresh database before the MR is reviewed. If the review leads
-   to large changes in the MR, do this again once the review is complete.
-1. For more complex migrations, write tests.
-1. Merge requests **must** adhere to the [merge request performance
-   guidelines](doc/development/merge_request_performance_guidelines.md).
-1. For tests that use Capybara or PhantomJS, see this [article on how
-   to write reliable asynchronous tests](https://robots.thoughtbot.com/write-reliable-asynchronous-integration-tests-with-capybara).
-
-Please keep the change in a single MR **as small as possible**. If you want to
-contribute a large feature think very hard what the minimum viable change is.
-Can you split the functionality? Can you only submit the backend/API code? Can
-you start with a very simple UI? Can you do part of the refactor? The increased
-reviewability of small MRs that leads to higher code quality is more important
-to us than having a minimal commit log. The smaller an MR is the more likely it
-is it will be merged (quickly). After that you can send more MRs to enhance it.
-The ['How to get faster PR reviews' document of Kubernetes](https://github.com/kubernetes/community/blob/master/contributors/devel/faster_reviews.md) also has some great points regarding this.
-
-For examples of feedback on merge requests please look at already
-[closed merge requests][closed-merge-requests]. If you would like quick feedback
-on your merge request feel free to mention someone from the [core team] or one
-of the [Merge request coaches][team].
-Please ensure that your merge request meets the contribution acceptance criteria.
-
-When having your code reviewed and when reviewing merge requests please take the
-[code review guidelines](doc/development/code_review.md) into account.
-
-### Contribution acceptance criteria
-
-1. The change is as small as possible
-1. Include proper tests and make all tests pass (unless it contains a test
-   exposing a bug in existing code). Every new class should have corresponding
-   unit tests, even if the class is exercised at a higher level, such as a feature test.
-1. If you suspect a failing CI build is unrelated to your contribution, you may
-   try and restart the failing CI job or ask a developer to fix the
-   aforementioned failing test
-1. Your MR initially contains a single commit (please use `git rebase -i` to
-   squash commits)
-1. Your changes can merge without problems (if not please rebase if you're the
-   only one working on your feature branch, otherwise, merge `master`)
-1. Does not break any existing functionality
-1. Fixes one specific issue or implements one specific feature (do not combine
-   things, send separate merge requests if needed)
-1. Migrations should do only one thing (e.g., either create a table, move data
-   to a new table or remove an old table) to aid retrying on failure
-1. Keeps the GitLab code base clean and well structured
-1. Contains functionality we think other users will benefit from too
-1. Doesn't add configuration options or settings options since they complicate
-   making and testing future changes
-1. Changes do not adversely degrade performance.
-   - Avoid repeated polling of endpoints that require a significant amount of overhead
-   - Check for N+1 queries via the SQL log or [`QueryRecorder`](https://docs.gitlab.com/ce/development/merge_request_performance_guidelines.html)
-   - Avoid repeated access of filesystem
-1. If you need polling to support real-time features, please use
-   [polling with ETag caching][polling-etag].
-1. Changes after submitting the merge request should be in separate commits
-   (no squashing).
-1. It conforms to the [style guides](#style-guides) and the following:
-    - If your change touches a line that does not follow the style, modify the
-      entire line to follow it. This prevents linting tools from generating warnings.
-    - Don't touch neighbouring lines. As an exception, automatic mass
-      refactoring modifications may leave style non-compliant.
-1. If the merge request adds any new libraries (gems, JavaScript libraries,
-   etc.), they should conform to our [Licensing guidelines][license-finder-doc].
-   See the instructions in that document for help if your MR fails the
-   "license-finder" test with a "Dependencies that need approval" error.
-1. The merge request meets the [definition of done](#definition-of-done).
-
-## Definition of done
+This [documentation](doc/development/contributing/merge_request_workflow.md) has been moved.
 
-If you contribute to GitLab please know that changes involve more than just
-code. We have the following [definition of done][definition-of-done]. Please ensure you support
-the feature you contribute through all of these steps.
-
-1. Description explaining the relevancy (see following item)
-1. Working and clean code that is commented where needed
-1. [Unit, integration, and system tests][testing] that pass on the CI server
-1. Performance/scalability implications have been considered, addressed, and tested
-1. [Documented][doc-guidelines] in the `/doc` directory
-1. [Changelog entry added][changelog], if necessary
-1. Reviewed and any concerns are addressed
-1. Merged by a project maintainer
-1. Added to the release blog article, if relevant
-1. Added to [the website](https://gitlab.com/gitlab-com/www-gitlab-com/), if relevant
-1. Community questions answered
-1. Answers to questions radiated (in docs/wiki/support etc.)
-
-If you add a dependency in GitLab (such as an operating system package) please
-consider updating the following and note the applicability of each in your

-## Style guides
-
-1.  [Ruby](https://github.com/bbatsov/ruby-style-guide).
-    Important sections include [Source Code Layout][rss-source] and
-    [Naming][rss-naming]. Use:
-    - multi-line method chaining style **Option A**: dot `.` on the second line
-    - string literal quoting style **Option A**: single quoted by default
-1.  [Rails](https://github.com/bbatsov/rails-style-guide)
-1.  [Newlines styleguide][newlines-styleguide]
-1.  [Testing][testing]
-1.  [JavaScript styleguide][js-styleguide]
-1.  [SCSS styleguide][scss-styleguide]
-1.  [Shell commands](doc/development/shell_commands.md) created by GitLab
-    contributors to enhance security

-    present time and never use past tense (has been/was). For example instead
-    of _prohibited this user from being saved due to the following errors:_ the
-    text should be _sorry, we could not create your account because:_
-1.  Code should be written in [US English][us-english]
-
-This is also the style used by linting tools such as
-[RuboCop](https://github.com/bbatsov/rubocop),
-[PullReview](https://www.pullreview.com/) and [Hound CI](https://houndci.com).
-
-## Code of conduct
-
-As contributors and maintainers of this project, we pledge to respect all
-people who contribute through reporting issues, posting feature requests,
-updating documentation, submitting pull requests or patches, and other
-activities.
-
-We are committed to making participation in this project a harassment-free
-experience for everyone, regardless of level of experience, gender, gender
-identity and expression, sexual orientation, disability, personal appearance,
-body size, race, ethnicity, age, or religion.
-
-Examples of unacceptable behavior by participants include the use of sexual
-language or imagery, derogatory comments or personal attacks, trolling, public
-or private harassment, insults, or other unprofessional conduct.
-
-Project maintainers have the right and responsibility to remove, edit, or
-reject comments, commits, code, wiki edits, issues, and other contributions
-that are not aligned to this Code of Conduct. Project maintainers who do not
-follow the Code of Conduct may be removed from the project team.
-
-This code of conduct applies both within project spaces and in public spaces
-when an individual is representing the project or its community.
-
-Instances of abusive, harassing, or otherwise unacceptable behavior can be
-reported by emailing `contact@gitlab.com`.
-
-This Code of Conduct is adapted from the [Contributor Covenant][contributor-covenant], version 1.1.0,
-available at [http://contributor-covenant.org/version/1/1/0/](http://contributor-covenant.org/version/1/1/0/).
-
-## Contribution Flow
-
-When contributing to GitLab, your merge request is subject to review by merge request maintainers of a particular specialty.
-
-When you submit code to GitLab, we really want it to get merged, but there will be times when it will not be merged.
+### Contribution acceptance criteria
 
-When maintainers are reading through a merge request they may request guidance from other maintainers. If merge request maintainers conclude that the code should not be merged, our reasons will be fully disclosed. If it has been decided that the code quality is not up to GitLab’s standards, the merge request maintainer will refer the author to our docs and code style guides, and provide some guidance.
+This [documentation](doc/development/contributing/merge_request_workflow.md) has been moved.
 
-Sometimes style guides will be followed but the code will lack structural integrity, or the maintainer will have reservations about the code’s overall quality. When there is a reservation the maintainer will inform the author and provide some guidance.  The author may then choose to update the merge request. Once the merge request has been updated and reassigned to the maintainer, they will review the code again. Once the code has been resubmitted any number of times, the maintainer may choose to close the merge request with a summary of why it will not be merged, as well as some guidance. If the merge request is closed the maintainer will be open to discussion as to how to improve the code so it can be approved in the future.
 
-GitLab will do its best to review community contributions as quickly as possible. Specially appointed developers review community contributions daily. You may take a look at the [team page](https://about.gitlab.com/team/) for the merge request coach who specializes in the type of code you have written and mention them in the merge request.  For example, if you have written some JavaScript in your code then you should mention the frontend merge request coach. If your code has multiple disciplines you may mention multiple merge request coaches.
+## Definition of done
 
-GitLab receives a lot of community contributions, so if your code has not been reviewed within 4 days of its initial submission feel free to re-mention the appropriate merge request coach.
+This [documentation](doc/development/contributing/merge_request_workflow.md)) has been moved.
 
-When submitting code to GitLab, you may feel that your contribution requires the aid of an external library. If your code includes an external library please provide a link to the library, as well as reasons for including it.
 
-When your code contains more than 500 changes, any major breaking changes, or an external library, `@mention` a maintainer in the merge request. If you are not sure who to mention, the reviewer will add one early in the merge request process.

+
+## Implement design & UI elements
+
+For guidance on UX implementation at GitLab, please refer to our [Design System](https://design.gitlab.com/).
+
+The UX team uses labels to manage their workflow.
+
+The  ~"UX" label on an issue is a signal to the UX team that it will need UX attention.
+To better understand the priority by which UX tackles issues, see the [UX section](https://about.gitlab.com/handbook/engineering/ux) of the handbook.
+
+Once an issue has been worked on and is ready for development, a UXer removes the ~"UX" label and applies the ~"UX ready" label to that issue.
+
+The UX team has a special type label called ~"design artifact". This label indicates that the final output
+for an issue is a UX solution/design. The solution will be developed by frontend and/or backend in a subsequent milestone.
+Any issue labeled ~"design artifact" should not also be labeled ~"frontend" or ~"backend" since no development is
+needed until the solution has been decided.
+
+~"design artifact" issues are like any other issue and should contain a milestone label, ~"Deliverable" or ~"Stretch", when scheduled in the current milestone.
+
+To prevent the misunderstanding that a feature will be be delivered in the
+assigned milestone, when only UX design is planned for that milestone, the
+Product Manager should create a separate issue for the ~"design artifact",
+assign the ~UX, ~"design artifact" and ~"Deliverable" labels, add a milestone
+and use a title that makes it clear that the scheduled issue is design only
+(e.g. `Design exploration for XYZ`).
+
+When the ~"design artifact" issue has been completed, the UXer removes the ~UX
+label, adds the ~"UX ready" label and closes the issue. This indicates the
+design artifact is complete. The UXer will also copy the designs to related
+issues for implementation in an upcoming milestone.
+
+## Style guides
+
+1.  [Ruby](https://github.com/bbatsov/ruby-style-guide).
+    Important sections include [Source Code Layout][rss-source] and
+    [Naming][rss-naming]. Use:
+    - multi-line method chaining style **Option A**: dot `.` on the second line
+    - string literal quoting style **Option A**: single quoted by default
+1.  [Rails](https://github.com/bbatsov/rails-style-guide)
+1.  [Newlines styleguide][newlines-styleguide]
+1.  [Testing][testing]
+1.  [JavaScript styleguide][js-styleguide]
+1.  [SCSS styleguide][scss-styleguide]
+1.  [Shell commands](../shell_commands.md) created by GitLab
+    contributors to enhance security
+1.  [Database Migrations](../migration_style_guide.md)
+1.  [Markdown](http://www.cirosantilli.com/markdown-styleguide)
+1.  [Documentation styleguide](https://docs.gitlab.com/ee/development/documentation/styleguide.html)
+1.  Interface text should be written subjectively instead of objectively. It
+    should be the GitLab core team addressing a person. It should be written in
+    present time and never use past tense (has been/was). For example instead
+    of _prohibited this user from being saved due to the following errors:_ the
+    text should be _sorry, we could not create your account because:_
+1.  Code should be written in [US English][us-english]
+
+This is also the style used by linting tools such as
+[RuboCop](https://github.com/bbatsov/rubocop),
+[PullReview](https://www.pullreview.com/) and [Hound CI](https://houndci.com).

+## Contribute to GitLab
+
+For a first-time step-by-step guide to the contribution process, see
+["Contributing to GitLab"](https://about.gitlab.com/contributing/).
+
+Thank you for your interest in contributing to GitLab. This guide details how
+to contribute to GitLab in a way that is efficient for everyone.
+
+Looking for something to work on? Look for issues with the label [Accepting Merge Requests](#i-want-to-contribute).
+
+GitLab comes into two flavors, GitLab Community Edition (CE) our free and open
+source edition, and GitLab Enterprise Edition (EE) which is our commercial
+edition. Throughout this guide you will see references to CE and EE for
+abbreviation.
+
+If you have read this guide and want to know how the GitLab [core team]
+operates please see [the GitLab contributing process](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/PROCESS.md).

+
+## Closing policy for issues and merge requests
+
+GitLab is a popular open source project and the capacity to deal with issues
+and merge requests is limited. Out of respect for our volunteers, issues and
+merge requests not in line with the guidelines listed in this document may be
+closed without notice.
+
+Please treat our volunteers with courtesy and respect, it will go a long way
+towards getting your issue resolved.
+
+Issues and merge requests should be in English and contain appropriate language
+for audiences of all ages.
+
+If a contributor is no longer actively working on a submitted merge request
+we can decide that the merge request will be finished by one of our
+[Merge request coaches][team] or close the merge request. We make this decision
+based on how important the change is for our product vision. If a Merge request
+coach is going to finish the merge request we assign the
+~"coach will finish" label.
+
+## Helping others
+
+Please help other GitLab users when you can.
+The methods people will use to seek help can be found on the [getting help page][getting-help].
+
+Sign up for the mailing list, answer GitLab questions on StackOverflow or
+respond in the IRC channel. You can also sign up on [CodeTriage][codetriage] to help with
+the remaining issues on the GitHub issue tracker.
+
+## I want to contribute!
+
+If you want to contribute to GitLab [issues with the label `Accepting Merge Requests` and small weight][accepting-mrs-weight]
+is a great place to start. Issues with a lower weight (1 or 2) are deemed
+suitable for beginners. These issues will be of reasonable size and challenge,
+for anyone to start contributing to GitLab. If you have any questions or need help visit [Getting Help](https://about.gitlab.com/getting-help/#discussion) to
+learn how to communicate with GitLab. If you're looking for a Gitter or Slack channel
+please consider we favor
+[asynchronous communication](https://about.gitlab.com/handbook/communication/#internal-communication) over real time communication. Thanks for your contribution!
+
+## Contribution Flow
+
+When contributing to GitLab, your merge request is subject to review by merge request maintainers of a particular specialty.
+
+When you submit code to GitLab, we really want it to get merged, but there will be times when it will not be merged.
+
+When maintainers are reading through a merge request they may request guidance from other maintainers. If merge request maintainers conclude that the code should not be merged, our reasons will be fully disclosed. If it has been decided that the code quality is not up to GitLab’s standards, the merge request maintainer will refer the author to our docs and code style guides, and provide some guidance.
+
+Sometimes style guides will be followed but the code will lack structural integrity, or the maintainer will have reservations about the code’s overall quality. When there is a reservation the maintainer will inform the author and provide some guidance.  The author may then choose to update the merge request. Once the merge request has been updated and reassigned to the maintainer, they will review the code again. Once the code has been resubmitted any number of times, the maintainer may choose to close the merge request with a summary of why it will not be merged, as well as some guidance. If the merge request is closed the maintainer will be open to discussion as to how to improve the code so it can be approved in the future.
+
+GitLab will do its best to review community contributions as quickly as possible. Specially appointed developers review community contributions daily. You may take a look at the [team page](https://about.gitlab.com/team/) for the merge request coach who specializes in the type of code you have written and mention them in the merge request.  For example, if you have written some JavaScript in your code then you should mention the frontend merge request coach. If your code has multiple disciplines you may mention multiple merge request coaches.
+
+GitLab receives a lot of community contributions, so if your code has not been reviewed within 4 days of its initial submission feel free to re-mention the appropriate merge request coach.
+
+When submitting code to GitLab, you may feel that your contribution requires the aid of an external library. If your code includes an external library please provide a link to the library, as well as reasons for including it.
+
+When your code contains more than 500 changes, any major breaking changes, or an external library, `@mention` a maintainer in the merge request. If you are not sure who to mention, the reviewer will add one early in the merge request process.

+
+## Workflow labels
+
+To allow for asynchronous issue handling, we use [milestones][milestones-page]
+and [labels][labels-page]. Leads and product managers handle most of the
+scheduling into milestones. Labelling is a task for everyone.
+
+Most issues will have labels for at least one of the following:
+
+- Type: ~"feature proposal", ~bug, ~customer, etc.
+- Subject: ~wiki, ~"container registry", ~ldap, ~api, ~frontend, etc.
+- Team: ~"CI/CD", ~Plan, ~Manage, ~Quality, etc.
+- Release Scoping: ~Deliverable, ~Stretch, ~"Next Patch Release"
+- Priority: ~P1, ~P2, ~P3, ~P4
+- Severity: ~S1, ~S2, ~S3, ~S4
+
+All labels, their meaning and priority are defined on the
+[labels page][labels-page].
+
+If you come across an issue that has none of these, and you're allowed to set
+labels, you can _always_ add the team and type, and often also the subject.
+
+[milestones-page]: https://gitlab.com/gitlab-org/gitlab-ce/milestones
+[labels-page]: https://gitlab.com/gitlab-org/gitlab-ce/labels
+
+### Type labels
+
+Type labels are very important. They define what kind of issue this is. Every
+issue should have one or more.
+
+Examples of type labels are ~"feature proposal", ~bug, ~customer, ~security,
+and ~"direction".
+
+A number of type labels have a priority assigned to them, which automatically
+makes them float to the top, depending on their importance.
+
+Type labels are always lowercase, and can have any color, besides blue (which is
+already reserved for subject labels).
+
+The descriptions on the [labels page][labels-page] explain what falls under each type label.
+
+### Subject labels
+
+Subject labels are labels that define what area or feature of GitLab this issue
+hits. They are not always necessary, but very convenient.
+
+Examples of subject labels are ~wiki, ~ldap, ~api,
+~issues, ~"merge requests", ~labels, and ~"container registry".
+
+If you are an expert in a particular area, it makes it easier to find issues to
+work on. You can also subscribe to those labels to receive an email each time an
+issue is labeled with a subject label corresponding to your expertise.
+
+Subject labels are always all-lowercase.
+
+### Team labels
+
+Team labels specify what team is responsible for this issue.
+Assigning a team label makes sure issues get the attention of the appropriate
+people.
+
+The current team labels are:
+
+- ~Configuration
+- ~"CI/CD"
+- ~Create
+- ~Distribution
+- ~Documentation
+- ~Geo
+- ~Gitaly
+- ~Manage
+- ~Monitoring
+- ~Plan
+- ~Quality
+- ~Release
+- ~Secure
+- ~UX
+
+The descriptions on the [labels page][labels-page] explain what falls under the
+responsibility of each team.
+
+Within those team labels, we also have the ~backend and ~frontend labels to
+indicate if an issue needs backend work, frontend work, or both.
+
+Team labels are always capitalized so that they show up as the first label for
+any issue.
+
+### Release Scoping labels
+
+Release Scoping labels help us clearly communicate expectations of the work for the
+release. There are three levels of Release Scoping labels:
+
+- ~Deliverable: Issues that are expected to be delivered in the current
+  milestone.
+- ~Stretch: Issues that are a stretch goal for delivering in the current
+  milestone. If these issues are not done in the current release, they will
+  strongly be considered for the next release.
+- ~"Next Patch Release": Issues to put in the next patch release. Work on these
+  first, and add the "Pick Into X" label to the merge request, along with the
+  appropriate milestone.
+
+Each issue scheduled for the current milestone should be labeled ~Deliverable
+or ~"Stretch". Any open issue for a previous milestone should be labeled
+~"Next Patch Release", or otherwise rescheduled to a different milestone.
+
+### Priority labels
+
+Priority labels help us define the time a ~bug fix should be completed. Priority determines how quickly the defect turnaround time must be.
+If there are multiple defects, the priority decides which defect has to be fixed immediately versus later.
+This label documents the planned timeline & urgency which is used to measure against our actual SLA on delivering ~bug fixes.
+
+| Label | Meaning         | Estimate time to fix                                             |
+|-------|-----------------|------------------------------------------------------------------|
+| ~P1   | Urgent Priority | The current release + potentially immediate hotfix to GitLab.com |
+| ~P2   | High Priority   | The next release                                                 |
+| ~P3   | Medium Priority | Within the next 3 releases (approx one quarter)                  |
+| ~P4   | Low Priority    | Anything outside the next 3 releases (approx beyond one quarter) |
+
+### Severity labels
+
+Severity labels help us clearly communicate the impact of a ~bug on users.
+
+| Label | Meaning           | Impact on Functionality                               | Example |
+|-------|-------------------|-------------------------------------------------------|---------|
+| ~S1   | Blocker           | Outage, broken feature with no workaround             | Unable to create an issue. Data corruption/loss. Security breach. |
+| ~S2   | Critical Severity | Broken Feature, workaround too complex & unacceptable | Can push commits, but only via the command line. |
+| ~S3   | Major Severity    | Broken Feature, workaround acceptable                 | Can create merge requests only from the Merge Requests page, not through the Issue. |
+| ~S4   | Low Severity      | Functionality inconvenience or cosmetic issue         | Label colors are incorrect / not being displayed. |
+
+#### Severity impact guidance
+
+Severity levels can be applied further depending on the facet of the impact; e.g. Affected customers, GitLab.com availability, performance and etc. The below is a guideline.
+
+| Severity | Affected Customers/Users                                            | GitLab.com Availability                            |  Performance Degradation     |
+|----------|---------------------------------------------------------------------|----------------------------------------------------|------------------------------|
+| ~S1      | >50% users affected (possible company extinction level event)       | Significant impact on all of GitLab.com            |                              |
+| ~S2      | Many users or multiple paid customers affected (but not apocalyptic)| Significant impact on large portions of GitLab.com | Degradation is guaranteed to occur in the near future |
+| ~S3      | A few users or a single paid customer affected                      | Limited impact on important portions of GitLab.com | Degradation is likely to occur in the near future     |
+| ~S4      | No paid users/customer affected, or expected to in the near future  | Minor impact on on GitLab.com                      | Degradation _may_ occur but it's not likely           |
+
+### Label for community contributors
+
+Issues that are beneficial to our users, 'nice to haves', that we currently do
+not have the capacity for or want to give the priority to, are labeled as
+~"Accepting Merge Requests", so the community can make a contribution.
+
+Community contributors can submit merge requests for any issue they want, but
+the ~"Accepting Merge Requests" label has a special meaning. It points to
+changes that:
+
+1. We already agreed on,
+1. Are well-defined,
+1. Are likely to get accepted by a maintainer.
+
+We want to avoid a situation when a contributor picks an
+~"Accepting Merge Requests" issue and then their merge request gets closed,
+because we realize that it does not fit our vision, or we want to solve it in a
+different way.
+
+We add the ~"Accepting Merge Requests" label to:
+
+- Low priority ~bug issues (i.e. we do not add it to the bugs that we want to
+solve in the ~"Next Patch Release")
+- Small ~"feature proposal"
+- Small ~"technical debt" issues
+
+After adding the ~"Accepting Merge Requests" label, we try to estimate the
+[weight](#issue-weight) of the issue. We use issue weight to let contributors
+know how difficult the issue is. Additionally:
+
+- We advertise ["Accepting Merge Requests" issues with weight < 5][up-for-grabs]
+  as suitable for people that have never contributed to GitLab before on the
+  [Up For Grabs campaign](http://up-for-grabs.net)
+- We encourage people that have never contributed to any open source project to
+  look for ["Accepting Merge Requests" issues with a weight of 1][firt-timers]
+
+If you've decided that you would like to work on an issue, please @-mention
+the [appropriate product manager](https://about.gitlab.com/handbook/product/#who-to-talk-to-for-what)
+as soon as possible. The product manager will then pull in appropriate GitLab team
+members to further discuss scope, design, and technical considerations. This will
+ensure that that your contribution is aligned with the GitLab product and minimize
+any rework and delay in getting it merged into master.
+
+GitLab team members who apply the ~"Accepting Merge Requests" label to an issue
+should update the issue description with a responsible product manager, inviting
+any potential community contributor to @-mention per above.
+
+[up-for-grabs]: https://gitlab.com/gitlab-org/gitlab-ce/issues?label_name=Accepting+Merge+Requests&scope=all&sort=weight_asc&state=opened
+[firt-timers]: https://gitlab.com/gitlab-org/gitlab-ce/issues?label_name%5B%5D=Accepting+Merge+Requests&scope=all&sort=upvotes_desc&state=opened&weight=1
+
+
+### Issue triaging
+
+Our issue triage policies are [described in our handbook]. You are very welcome
+to help the GitLab team triage issues. We also organize [issue bash events] once
+every quarter.
+
+The most important thing is making sure valid issues receive feedback from the
+development team. Therefore the priority is mentioning developers that can help
+on those issues. Please select someone with relevant experience from the
+[GitLab team][team]. If there is nobody mentioned with that expertise look in
+the commit history for the affected files to find someone.
+
+We also use [GitLab Triage] to automate some triaging policies. This is
+currently setup as a [scheduled pipeline] running on [quality/triage-ops]
+project.
+
+[described in our handbook]: https://about.gitlab.com/handbook/engineering/issue-triage/
+[issue bash events]: https://gitlab.com/gitlab-org/gitlab-ce/issues/17815
+[GitLab Triage]: https://gitlab.com/gitlab-org/gitlab-triage
+[scheduled pipeline]: https://gitlab.com/gitlab-org/quality/triage-ops/pipeline_schedules/10512/edit
+[quality/triage-ops]: https://gitlab.com/gitlab-org/quality/triage-ops
+
+### Feature proposals
+
+To create a feature proposal for CE, open an issue on the
+[issue tracker of CE][ce-tracker].
+
+For feature proposals for EE, open an issue on the
+[issue tracker of EE][ee-tracker].
+
+In order to help track the feature proposals, we have created a
+[`feature proposal`][fpl] label. For the time being, users that are not members
+of the project cannot add labels. You can instead ask one of the [core team]
+members to add the label ~"feature proposal" to the issue or add the following
+code snippet right after your description in a new line: `~"feature proposal"`.
+
+Please keep feature proposals as small and simple as possible, complex ones
+might be edited to make them small and simple.
+
+Please submit Feature Proposals using the ['Feature Proposal' issue template](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/.gitlab/issue_templates/Feature Proposal.md) provided on the issue tracker.
+
+For changes in the interface, it is helpful to include a mockup. Issues that add to, or change, the interface should
+be given the ~"UX" label. This will allow the UX team to provide input and guidance. You may
+need to ask one of the [core team] members to add the label, if you do not have permissions to do it by yourself.
+
+If you want to create something yourself, consider opening an issue first to
+discuss whether it is interesting to include this in GitLab.
+
+### Issue tracker guidelines
+
+**[Search the issue tracker][ce-tracker]** for similar entries before
+submitting your own, there's a good chance somebody else had the same issue or
+feature proposal. Show your support with an award emoji and/or join the
+discussion.
+
+Please submit bugs using the ['Bug' issue template](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/.gitlab/issue_templates/Bug.md) provided on the issue tracker.
+The text in the parenthesis is there to help you with what to include. Omit it
+when submitting the actual issue. You can copy-paste it and then edit as you
+see fit.
+
+### Issue weight
+
+Issue weight allows us to get an idea of the amount of work required to solve
+one or multiple issues. This makes it possible to schedule work more accurately.
+
+You are encouraged to set the weight of any issue. Following the guidelines
+below will make it easy to manage this, without unnecessary overhead.
+
+1. Set weight for any issue at the earliest possible convenience
+1. If you don't agree with a set weight, discuss with other developers until
+consensus is reached about the weight
+1. Issue weights are an abstract measurement of complexity of the issue. Do not
+relate issue weight directly to time. This is called [anchoring](https://en.wikipedia.org/wiki/Anchoring)
+and something you want to avoid.
+1. Something that has a weight of 1 (or no weight) is really small and simple.
+Something that is 9 is rewriting a large fundamental part of GitLab,
+which might lead to many hard problems to solve. Changing some text in GitLab
+is probably 1, adding a new Git Hook maybe 4 or 5, big features 7-9.
+1. If something is very large, it should probably be split up in multiple
+issues or chunks. You can simply not set the weight of a parent issue and set
+weights to children issues.
+
+### Regression issues
+
+Every monthly release has a corresponding issue on the CE issue tracker to keep
+track of functionality broken by that release and any fixes that need to be
+included in a patch release (see [8.3 Regressions] as an example).
+
+As outlined in the issue description, the intended workflow is to post one note
+with a reference to an issue describing the regression, and then to update that
+note with a reference to the merge request that fixes it as it becomes available.
+
+If you're a contributor who doesn't have the required permissions to update
+other users' notes, please post a new note with a reference to both the issue
+and the merge request.
+
+The release manager will [update the notes] in the regression issue as fixes are
+addressed.
+
+[8.3 Regressions]: https://gitlab.com/gitlab-org/gitlab-ce/issues/4127
+[update the notes]: https://gitlab.com/gitlab-org/release-tools/blob/master/doc/pro-tips.md#update-the-regression-issue
+
+### Technical and UX debt
+
+In order to track things that can be improved in GitLab's codebase,
+we use the ~"technical debt" label in [GitLab's issue tracker][ce-tracker].
+For user experience improvements, we use the ~"UX debt" label.
+
+These labels should be added to issues that describe things that can be improved,
+shortcuts that have been taken, features that need additional attention, and all
+other things that have been left behind due to high velocity of development.
+For example, code that needs refactoring should use the ~"technical debt" label,
+user experience refinements should use the ~"UX debt" label.
+
+Everyone can create an issue, though you may need to ask for adding a specific
+label, if you do not have permissions to do it by yourself. Additional labels
+can be combined with these labels, to make it easier to schedule
+the improvements for a release.
+
+Issues tagged with these labels have the same priority like issues
+that describe a new feature to be introduced in GitLab, and should be scheduled
+for a release by the appropriate person.
+
+Make sure to mention the merge request that the ~"technical debt" issue or
+~"UX debt" issue is associated with in the description of the issue.
+
+### Stewardship
+
+For issues related to the open source stewardship of GitLab,
+there is the ~"stewardship" label.
+
+This label is to be used for issues in which the stewardship of GitLab
+is a topic of discussion. For instance if GitLab Inc. is planning to add
+features from GitLab EE to GitLab CE, related issues would be labelled with
+~"stewardship".
+
+A recent example of this was the issue for
+[bringing the time tracking API to GitLab CE][time-tracking-issue].
+
+[time-tracking-issue]: https://gitlab.com/gitlab-org/gitlab-ce/issues/25517#note_20019084

+## Merge requests
+
+We welcome merge requests with fixes and improvements to GitLab code, tests,
+and/or documentation. The issues that are specifically suitable for
+community contributions are listed with the label
+[`Accepting Merge Requests` on our issue tracker for CE][accepting-mrs-ce]
+and [EE][accepting-mrs-ee], but you are free to contribute to any other issue
+you want.
+
+Please note that if an issue is marked for the current milestone either before
+or while you are working on it, a team member may take over the merge request
+in order to ensure the work is finished before the release date.
+
+If you want to add a new feature that is not labeled it is best to first create
+a feedback issue (if there isn't one already) and leave a comment asking for it
+to be marked as `Accepting Merge Requests`. Please include screenshots or
+wireframes if the feature will also change the UI.
+
+Merge requests should be opened at [GitLab.com][gitlab-mr-tracker].
+
+If you are new to GitLab development (or web development in general), see the
+[I want to contribute!](#i-want-to-contribute) section to get you started with
+some potentially easy issues.
+
+To start with GitLab development download the [GitLab Development Kit][gdk] and
+see the [Development section](../README.md) for some guidelines.
+
+### Merge request guidelines
+
+If you can, please submit a merge request with the fix or improvements
+including tests. If you don't know how to fix the issue but can write a test
+that exposes the issue we will accept that as well. In general bug fixes that
+include a regression test are merged quickly while new features without proper
+tests are least likely to receive timely feedback. The workflow to make a merge
+request is as follows:
+
+1. Fork the project into your personal space on GitLab.com
+1. Create a feature branch, branch away from `master`
+1. Write [tests](https://docs.gitlab.com/ee/development/rake_tasks.html#run-tests) and code
+1. [Generate a changelog entry with `bin/changelog`][changelog]
+1. If you are writing documentation, make sure to follow the
+   [documentation guidelines][doc-guidelines]
+1. If you have multiple commits please combine them into a few logically
+  organized commits by [squashing them][git-squash]
+1. Push the commit(s) to your fork
+1. Submit a merge request (MR) to the `master` branch
+  1. Your merge request needs at least 1 approval but feel free to require more.
+    For instance if you're touching backend and frontend code, it's a good idea
+    to require 2 approvals: 1 from a backend maintainer and 1 from a frontend
+    maintainer
+  1. You don't have to select any approvers, but you can if you really want
+    specific people to approve your merge request
+1. The MR title should describe the change you want to make
+1. The MR description should give a motive for your change and the method you
+   used to achieve it.
+  1. If you are contributing code, fill in the template already provided in the
+     "Description" field.
+  1. If you are contributing documentation, choose `Documentation` from the
+     "Choose a template" menu and fill in the template.
+  1. Mention the issue(s) your merge request solves, using the `Solves #XXX` or
+    `Closes #XXX` syntax to auto-close the issue(s) once the merge request will
+    be merged.
+1. If you're allowed to, set a relevant milestone and labels
+1. If the MR changes the UI it should include *Before* and *After* screenshots
+1. If the MR changes CSS classes please include the list of affected pages,
+   `grep css-class ./app -R`
+1. Be prepared to answer questions and incorporate feedback even if requests
+   for this arrive weeks or months after your MR submission
+  1. If a discussion has been addressed, select the "Resolve discussion" button
+    beneath it to mark it resolved.
+1. If your MR touches code that executes shell commands, reads or opens files or
+   handles paths to files on disk, make sure it adheres to the
+   [shell command guidelines](../shell_commands.md)
+1. If your code creates new files on disk please read the
+   [shared files guidelines](../shared_files.md).
+1. When writing commit messages please follow
+   [these](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html)
+   [guidelines](http://chris.beams.io/posts/git-commit/).
+1. If your merge request adds one or more migrations, make sure to execute all
+   migrations on a fresh database before the MR is reviewed. If the review leads
+   to large changes in the MR, do this again once the review is complete.
+1. For more complex migrations, write tests.
+1. Merge requests **must** adhere to the [merge request performance
+   guidelines](../merge_request_performance_guidelines.md).
+1. For tests that use Capybara or PhantomJS, see this [article on how
+   to write reliable asynchronous tests](https://robots.thoughtbot.com/write-reliable-asynchronous-integration-tests-with-capybara).
+
+Please keep the change in a single MR **as small as possible**. If you want to
+contribute a large feature think very hard what the minimum viable change is.
+Can you split the functionality? Can you only submit the backend/API code? Can
+you start with a very simple UI? Can you do part of the refactor? The increased
+reviewability of small MRs that leads to higher code quality is more important
+to us than having a minimal commit log. The smaller an MR is the more likely it
+is it will be merged (quickly). After that you can send more MRs to enhance it.
+The ['How to get faster PR reviews' document of Kubernetes](https://github.com/kubernetes/community/blob/master/contributors/devel/faster_reviews.md) also has some great points regarding this.
+
+For examples of feedback on merge requests please look at already
+[closed merge requests][closed-merge-requests]. If you would like quick feedback
+on your merge request feel free to mention someone from the [core team] or one
+of the [Merge request coaches][team].
+Please ensure that your merge request meets the contribution acceptance criteria.
+
+When having your code reviewed and when reviewing merge requests please take the
+[code review guidelines](../code_review.md) into account.
+
+### Contribution acceptance criteria
+
+1. The change is as small as possible
+1. Include proper tests and make all tests pass (unless it contains a test
+   exposing a bug in existing code). Every new class should have corresponding
+   unit tests, even if the class is exercised at a higher level, such as a feature test.
+1. If you suspect a failing CI build is unrelated to your contribution, you may
+   try and restart the failing CI job or ask a developer to fix the
+   aforementioned failing test
+1. Your MR initially contains a single commit (please use `git rebase -i` to
+   squash commits)
+1. Your changes can merge without problems (if not please rebase if you're the
+   only one working on your feature branch, otherwise, merge `master`)
+1. Does not break any existing functionality
+1. Fixes one specific issue or implements one specific feature (do not combine
+   things, send separate merge requests if needed)
+1. Migrations should do only one thing (e.g., either create a table, move data
+   to a new table or remove an old table) to aid retrying on failure
+1. Keeps the GitLab code base clean and well structured
+1. Contains functionality we think other users will benefit from too
+1. Doesn't add configuration options or settings options since they complicate
+   making and testing future changes
+1. Changes do not adversely degrade performance.
+   - Avoid repeated polling of endpoints that require a significant amount of overhead
+   - Check for N+1 queries via the SQL log or [`QueryRecorder`](https://docs.gitlab.com/ce/development/mer ge_request_performance_guidelines.html)
+   - Avoid repeated access of filesystem
+1. If you need polling to support real-time features, please use
+   [polling with ETag caching][polling-etag].
+1. Changes after submitting the merge request should be in separate commits
+   (no squashing).
+1. It conforms to the [style guides](#style-guides) and the following:
+    - If your change touches a line that does not follow the style, modify the
+      entire line to follow it. This prevents linting tools from generating warnings.
+    - Don't touch neighbouring lines. As an exception, automatic mass
+      refactoring modifications may leave style non-compliant.
+1. If the merge request adds any new libraries (gems, JavaScript libraries,
+   etc.), they should conform to our [Licensing guidelines][license-finder-doc].
+   See the instructions in that document for help if your MR fails the
+   "license-finder" test with a "Dependencies that need approval" error.
+1. The merge request meets the [definition of done](#definition-of-done).
+
+## Definition of done
+
+If you contribute to GitLab please know that changes involve more than just
+code. We have the following [definition of done][definition-of-done]. Please ensure you support
+the feature you contribute through all of these steps.
+
+1. Description explaining the relevancy (see following item)
+1. Working and clean code that is commented where needed
+1. [Unit, integration, and system tests][testing] that pass on the CI server
+1. Performance/scalability implications have been considered, addressed, and tested
+1. [Documented][doc-guidelines] in the `/doc` directory
+1. [Changelog entry added][changelog], if necessary
+1. Reviewed and any concerns are addressed
+1. Merged by a project maintainer
+1. Added to the release blog article, if relevant
+1. Added to [the website](https://gitlab.com/gitlab-com/www-gitlab-com/), if relevant
+1. Community questions answered
+1. Answers to questions radiated (in docs/wiki/support etc.)
+
+If you add a dependency in GitLab (such as an operating system package) please
+consider updating the following and note the applicability of each in your
+merge request:
+
+1. Note the addition in the release blog post (create one if it doesn't exist yet) https://gitlab.com/gitlab-com/www-gitlab-com/merge_requests/
+1. Upgrade guide, for example https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/update/7.5-to-7.6.md
+1. Upgrader https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/update/upgrader.md#2-run-gitlab-upgrade-tool

+## Adding foreign-key constraints
+
+When adding a foreign-key constraint to either an existing or new
+column remember to also add a index on the column.
+
+This is _required_ if the foreign-key constraint specifies
+`ON DELETE CASCADE` or `ON DELETE SET NULL` behavior. On a cascading
+delete, the [corresponding record needs to be retrieved using an
+index](https://www.cybertec-postgresql.com/en/postgresql-indexes-and-foreign-keys/)
+(otherwise, we'd need to scan the whole table) for subsequent update or
+deletion.
+
+Here's an example where we add a new column with a foreign key
+constraint. Note it includes `index: true` to create an index for it.
+
+```ruby
+class Migration < ActiveRecord::Migration
+
+  def change
+    add_reference :model, :other_model, index: true, foreign_key: { on_delete: :cascade }
+  end
+end
+```
+
+When adding a foreign-key constraint to an existing column, we
+have to employ `add_concurrent_foreign_key` and `add_concurrent_index`
+instead of `add_reference`.
+
