 ## Project services
 
 Integration with services such as Campfire, Flowdock, Gemnasium, HipChat,
 Pivotal Tracker, and Slack are available in the form of a [Project Service][].
+You can find these within GitLab in the Services page under Project Settings if
+you are at least a master on the project.
+Project Services are a bit like plugins in that they allow a lot of freedom in
+adding functionality to GitLab. For example there is also a service that can
+send an email every time someone pushes new commits.
 
-[Project Service]: ../project_services/project_services.md
-
-## SSL certificate errors
-
-When trying to integrate GitLab with services that are using self-signed certificates,
-it is very likely that SSL certificate errors will occur on different parts of the
-application, most likely Sidekiq. There are 2 approaches you can take to solve this:
-
-1. Add the root certificate to the trusted chain of the OS.
-1. If using Omnibus, you can add the certificate to GitLab's trusted certificates.
-
-**OS main trusted chain**
+Because GitLab is open source we can ship with the code and tests for all
+plugins. This allows the community to keep the plugins up to date so that they
+always work in newer GitLab versions.
 
-This [resource](http://kb.kerio.com/product/kerio-connect/server-configuration/ssl-certificates/adding-trusted-root-certificates-to-the-server-1605.html)
-has all the information you need to add a certificate to the main trusted chain.
+For an overview of what projects services are available without logging in,
+please see the [project_services directory][projects-code].
 
-This [answer](http://superuser.com/questions/437330/how-do-you-add-a-certificate-authority-ca-to-ubuntu)
-at SuperUser also has relevant information.
-
-**Omnibus Trusted Chain**
-
-It is enough to concatenate the certificate to the main trusted certificate:
-
-```bash
-cat jira.pem >> /opt/gitlab/embedded/ssl/certs/cacert.pem
-```
-
-After that restart GitLab with:
-
-```bash
-sudo gitlab-ctl restart
-```

-# GitLab JIRA integration
+# GitLab Jira integration
 
-This document was moved under [project_services/jira](../project_services/jira.md).
+GitLab can be configured to interact with Jira. Configuration happens via
+username and password. Connecting to a Jira server via CAS is not possible.
+
+Each project can be configured to connect to a different Jira instance, see the
+[configuration](#configuration) section. If you have one Jira instance you can
+pre-fill the settings page with a default template. To configure the template
+see the [Services Templates][services-templates] document.
+
+Once the project is connected to Jira, you can reference and close the issues
+in Jira directly from GitLab.
+

+* [Configuration](#configuration)
+
+### Referencing Jira Issues
+
+When GitLab project has Jira issue tracker configured and enabled, mentioning
+Jira issue in GitLab will automatically add a comment in Jira issue with the
+link back to GitLab. This means that in comments in merge requests and commits
+referencing an issue, eg. `PROJECT-7`, will add a comment in Jira issue in the
+format:
+
+```
+ USER mentioned this issue in LINK_TO_THE_MENTION
+```
+
+* `USER` A user that mentioned the issue. This is the link to the user profile in GitLab.
+* `LINK_TO_THE_MENTION` Link to the origin of mention with a name of the entity where Jira issue was mentioned.
+Can be commit or merge request.
+
+![example of mentioning or closing the Jira issue](img/jira_issue_reference.png)
+
+---
+
+### Closing Jira Issues
+
+Jira issues can be closed directly from GitLab by using trigger words, eg.
+`Resolves PROJECT-1`, `Closes PROJECT-1` or `Fixes PROJECT-1`, in commits and
+merge requests. When a commit which contains the trigger word in the commit
+message is pushed, GitLab will add a comment in the mentioned Jira issue.
+
+For example, for project named `PROJECT` in Jira, we implemented a new feature
+and created a merge request in GitLab.
+
+This feature was requested in Jira issue `PROJECT-7`. Merge request in GitLab
+contains the improvement and in merge request description we say that this
+merge request `Closes PROJECT-7` issue.
+
+Once this merge request is merged, the Jira issue will be automatically closed
+with a link to the commit that resolved the issue.

+
+## Configuration
+
+### Configuring JIRA
+
+We need to create a user in JIRA which will have access to all projects that
+need to integrate with GitLab. Login to your JIRA instance as admin and under
+Administration go to User Management and create a new user.
+
+As an example, we'll create a user named `gitlab` and add it to `jira-developers`
+group.
+
+**It is important that the user `gitlab` has write-access to projects in JIRA**
+
+### Configuring GitLab
+
+JIRA configuration in GitLab is done via a project's **Services**.
+
+#### GitLab 7.8 and up with JIRA v6.x
+
+See next section.
+
+#### GitLab 7.8 and up
+
+_The currently supported JIRA versions are v6.x and v7.x._
+
+To enable JIRA integration in a project, navigate to the project's
+**Settings > Services > JIRA**.
+
+Fill in the required details on the page as described in the table below.
+
+| Field | Description |
+| ----- | ----------- |
+| `URL` | The base URL to the JIRA project which is being linked to this GitLab project. Ex. https://jira.example.com |
+| `Project key` | The short, all capital letter identifier for your JIRA project. |
+| `Username` | The username of the user created in [configuring JIRA step](#configuring-jira). |
+| `Password` |The password of the user created in [configuring JIRA step](#configuring-jira). |
+| `Jira issue transition` | This is the ID of a transition that moves issues to a closed state. You can find this number under JIRA workflow administration ([see screenshot](img/jira_workflow_screenshot.png)).  By default, this ID is `2` (in the example image, this is `2` as well) |
+
+After saving the configuration, your GitLab project will be able to interact
+with the linked JIRA project.

+#### GitLab 6.x-7.7 with JIRA v6.x
+
+_**Note:** GitLab versions 7.8 and up contain various integration improvements.
+We strongly recommend upgrading._
+
+In `gitlab.yml` enable the JIRA issue tracker section by
+[uncommenting these lines][jira-gitlab-yml]. This will make sure that all
+issues within GitLab are pointing to the JIRA issue tracker.
+
+After you set this, you will be able to close issues in JIRA by a commit in
+GitLab.
+
+Go to your project's **Settings** page and fill in the project name for the
+JIRA project:
+

+You can also enable the JIRA service that will allow you to interact with JIRA
+issues. Go to the **Settings > Services > JIRA** and:
+
+1. Tick the active check box to enable the service
+1. Supply the URL to JIRA server, for example http://jira.example.com
