+# Repository
+
+A [repository](https://git-scm.com/book/en/v2/Git-Basics-Getting-a-Git-Repository)
+is what you use to store your codebase in GitLab and change it with version control.
+A repository is part of a project, which has a lot of other features.
+
+## Create a repository
+
+To create a new repository, all you need to do is
+[create a new project](../../../gitlab-basics/create-project.md).
+
+Once you create a new project, you can add new files via UI
+(read the section below) or via command line.
+To add files from the command line, follow the instructions that will
+be presented on the screen when you create a new project, or read
+through them in the [command line basics](../../../gitlab-basics/start-using-git.md)
+documentation.
+
+> **Important:**
+For security reasons, when using the command line, we strongly recommend
+you to [connect with GitLab via SSH](../../../ssh/README.md).
+
+## Create and edit files
+
+Host your codebase in GitLab repositories by pushing your files to GitLab.
+You can either use the user interface (UI), or connect your local computer
+with GitLab [through the command line](../../../gitlab-basics/command-line-commands.md#start-working-on-your-project).
+
+To configure [GitLab CI/CD](../../../ci/README.md) to build, test, and deploy
+you code, add a file called [.`gitlab-ci.yml`](../../../ci/quick_start/README.md)
+to your repository's root.
+
+**From the user interface:**
+
+GitLab's UI allows you to perform lots of Git commands without having to
+touch the command line. Even if you use the command line regularly, sometimes
+it's easier to do so [via GitLab UI](web_editor.md):
+
+- [Create a file](web_editor.md#create-a-file)
+- [Upload a file](web_editor.md#upload-a-file)
+- [File templates](web_editor.md#template-dropdowns)
+- [Create a directory](web_editor.md#create-a-directory)
+- [Start a merge request](web_editor.md#tips)
+
+**From the command line:**
+
+To get started with the command line, please read through the
+[command line basics documentation](../../../gitlab-basics/command-line-commands.md).
+
+## Branches
+
+When you submit changes in a new branch, you create a new version
+of that project's file tree. Your branch contains all the changes
+you are presenting, which are detected by Git line by line.
+
+To continue your workflow, once you pushed your changes to a new branch,
+you can create a [merge request](../merge_requests/index.md), perform
+inline code review, and [discuss](../../discussions/index.md)
+your implementation with your team.
+You can live preview changes submitted to a new branch with
+[Review Apps](../../../ci/review_apps/index.md).
+
+With [GitLab Enterprise Edition](https://about.gitlab.com/gitlab-ee/)
+subscriptions, you can also request
+[approval](https://docs.gitlab.com/ee/user/project/merge_requests/merge_request_approvals.html#merge-request-approvals) from your managers.
+
+To create, delete, and branches via GitLab's UI:
+
+- [Create a branch](web_editor.md#create-a-new-branch)
+- [Protected branches](../protected_branches.md#protected-branches)
+- [Delete merged branches](branches/index.md#delete-merged-branches)
+
+Alternatively, you can use the
+[command line](../../../gitlab-basics/start-using-git.md#create-a-branch).
+
+To learn more about branching strategies read through the
+[GitLab Flow](../../../university/training/gitlab_flow.md) documentation.
+
+## Commits
+
+When you [commit your changes](https://git-scm.com/book/en/v2/Git-Basics-Recording-Changes-to-the-Repository),
+you are introducing those changes to your branch.
+Via command line, you can commit multiple times before pushing.
+
+- **Commit message:**
+A commit message is important to identity what is being changed and,
+more importantly, why. In GitLab, you can add keywords to the commit
+message that will perform one of the actions below:
+  - **Trigger a GitLab CI/CD pipeline:**
+  If you have your project configured with [GitLab CI/CD](../../../ci/README.md),
+  you will trigger a pipeline per push, not per commit.
+  - **Skip pipelines:**
+  You can add to you commit message the keyword
+  [`[ci skip]`](../../../ci/yaml/README.html#skipping-jobs)
+  and GitLab CI will skip that pipeline.
+  - **Cross-link issues and merge requests:**
+  [Cross-linking](../issues/crosslinking_issues.md#from-commit-messages)
+  is great to keep track of what's is somehow related in your workflow.
+  If you mention an issue or a merge request in a commit message, they will be shown
+  on their respective thread.
+- **Cherry-pick a commit:**
+In GitLab, you can
+[cherry-pick a commit](../merge_requests/cherry_pick_changes.md#cherry-picking-a-commit)
+right from the UI.
+- **Revert a commit:**
+Easily [revert a commit](../merge_requests/revert_changes.md#reverting-a-commit)
+from the UI to a selected branch.
+
+## Repository size
+
+In GitLab.com, your repository size limit it 10GB. For other instances,
+the repository size is limited by your system administrators.
+
+You can also [reduce a repository size using Git](reducing_the_repo_size_using_git.md).
+
+## Contributors
+
+All the contributors to your codebase are displayed under your project's **Settings > Contributors**.
+
+They are ordered from the collaborator with the greatest number
+of commits to the fewest, and displayed on a nice graph:
+
+![contributors to code](img/contributors_graph.png)
+
+## Repository graph
+
+The repository graph displays visually the Git flow strategy used in that repository:
+
+![repository Git flow](img/repo_graph.png)
+
+Find it under your project's **Repository > Graph**.
+
+## Compare
+
+Select branches to compare and view the changes inline:
+
+![compare branches](img/compare_branches.png)
+
+Find it under your project's **Repository > Compare**.
+
+## Locked files (EEP)
+
+Lock your files to prevent any conflicting changes.
+
+[File Locking](https://docs.gitlab.com/ee/user/project/file_lock.html) is available only in
+[GitLab Enterprise Edition Premium](https://about.gitlab.com/gitlab-ee/).
+
+## Repository's API
+
+You can access your repos via [repository API](../../../api/repositories.md).

doc/user/project/repository/reducing_the_repo_size_using_git.md

+# Reducing the repository size using Git
+
+A GitLab Entrerprise Edition administrator can set a [repository size limit][admin-repo-size]
+which will prevent you to exceed it.
+
+When a project has reached its size limit, you will not be able to push to it,
+create a new merge request, or merge existing ones. You will still be able to
+create new issues, and clone the project though. Uploading LFS objects will
+also be denied.
+
+In order to lift these restrictions, the administrator of the GitLab instance
+needs to increase the limit on the particular project that exceeded it or you
+need to instruct Git to rewrite changes.
+
+If you exceed the repository size limit, your first thought might be to remove
+some data, make a new commit and push back to the repository. Unfortunately,
+it's not so easy and that workflow won't work. Deleting files in a commit doesn't
+actually reduce the size of the repo since the earlier commits and blobs are
+still around. What you need to do is rewrite history with Git's
+[`filter-branch` option][gitscm].
+
+Note that even with that method, until `git gc` runs on the GitLab side, the
+"removed" commits and blobs will still be around. And if a commit was ever
+included in an MR, or if a build was run for a commit, or if a user commented
+on it, it will be kept around too. So, in these cases the size will not decrease.
+
+The only fool proof way to actually decrease the repository size is to prune all
+the unneeded stuff locally, and then create a new project on GitLab and start
+using that instead.
+
+With that being said, you can try reducing your repository size with the
+following method.
+
+## Using `git filter-branch` to purge files
+
+>
+**Warning:**
+Make sure to first make a copy of your repository since rewriting history will
+purge the files and information you are about to delete. Also make sure to
+inform any collaborators to not use `pull` after your changes, but use `rebase`.
+
+1. Navigate to your repository:
+
+    ```
+    cd my_repository/
+    ```
+
+1. Change to the branch you want to remove the big file from:
+
+    ```
+    git checkout master
+    ```
+
+1. Use `filter-branch` to remove the big file:
+
+    ```
+    git filter-branch --force --tree-filter 'rm -f path/to/big_file.mpg' HEAD
+    ```
+
+1. Instruct Git to purge the unwanted data:
+
+    ```
+    git reflog expire --expire=now --all && git gc --prune=now --aggressive
+    ```
+
+1. Lastly, force push to the repository:
+
+    ```
+    git push --force origin master
+    ```
+
+Your repository should now be below the size limit.
+
+>**Note:**
+As an alternative to `filter-branch`, you can use the `bfg` tool with a
+command like: `bfg --delete-files path/to/big_file.mpg`. Read the
+[BFG Repo-Cleaner][bfg] documentation for more information.
