 The `gitlab` Helm chart deploys just GitLab into your Kubernetes cluster, and offers extensive configuration options. This chart requires advanced knowledge of Kubernetes to successfully use.

Due to the difficulty in supporting upgrades to the `omnibus-gitlab` chart, migrating will require exporting data out of this instance and importing it into the new deployment.

+# Fast-forward merge requests
+
+Retain a linear Git history and a way to accept merge requests without
+creating merge commits.
+
+## Overview
+
+When the fast-forward merge ([`--ff-only`][ffonly]) setting is enabled, no merge
+commits will be created and all merges are fast-forwarded, which means that
+merging is only allowed if the branch could be fast-forwarded.
+
+When a fast-forward merge is not possible, the user must rebase the branch manually.
+
+## Use cases
+
+Sometimes, a workflow policy might mandate a clean commit history without
+merge commits. In such cases, the fast-forward merge is the perfect candidate.
+
+## Enabling fast-forward merges
+
+1. Navigate to your project's **Settings** and search for the 'Merge method'
+1. Select the **Fast-forward merge** option
+1. Hit **Save changes** for the changes to take effect
+
+Now, when you visit the merge request page, you will be able to accept it
+**only if a fast-forward merge is possible**.
+
+![Fast forward merge request](img/ff_merge_mr.png)
+
+If the target branch is ahead of the source branch, you need to rebase the
+source branch locally before you will be able to do a fast-forward merge.
