-
-### Checkout merge requests locally
-
-A merge request contains all the history from a repository, plus the additional
-commits added to the branch associated with the merge request. Here's a few
-tricks to checkout a merge request locally.
-
-Please note that you can checkout a merge request locally even if the source
-project is a fork (even a private fork) of the target project.
-
-#### Checkout locally by adding a git alias
-
-Add the following alias to your `~/.gitconfig`:
-
-```
-[alias]
-    mr = !sh -c 'git fetch $1 merge-requests/$2/head:mr-$1-$2 && git checkout mr-$1-$2' -
-```
-
-Now you can check out a particular merge request from any repository and any
-remote. For example, to check out the merge request with ID 5 as shown in GitLab
-from the `upstream` remote, do:
-
-```
-git mr upstream 5
-```
-
-This will fetch the merge request into a local `mr-upstream-5` branch and check
-it out.
-
-#### Checkout locally by modifying `.git/config` for a given repository
-
-Locate the section for your GitLab remote in the `.git/config` file. It looks
-like this:
-
-```
-[remote "origin"]
-  url = https://gitlab.com/gitlab-org/gitlab-ce.git
-  fetch = +refs/heads/*:refs/remotes/origin/*
-```
-
-You can open the file with:
-
-```
-git config -e
-```
-
-Now add the following line to the above section:
-
-```
-fetch = +refs/merge-requests/*/head:refs/remotes/origin/merge-requests/*
-```
-
-In the end, it should look like this:
-
-```
-[remote "origin"]
-  url = https://gitlab.com/gitlab-org/gitlab-ce.git
-  fetch = +refs/heads/*:refs/remotes/origin/*
-  fetch = +refs/merge-requests/*/head:refs/remotes/origin/merge-requests/*
-```
-
-Now you can fetch all the merge requests:
-
-```
-git fetch origin
-
-...
-From https://gitlab.com/gitlab-org/gitlab-ce.git
- * [new ref]         refs/merge-requests/1/head -> origin/merge-requests/1
- * [new ref]         refs/merge-requests/2/head -> origin/merge-requests/2
-...
-```
-
-And to check out a particular merge request:
-
-```
-git checkout origin/merge-requests/1
-```
