+# Fast-forward merge
+
+GitLab Enterprise Edition offers a way to accept merge requests without creating
+merge commits. If you prefer a linear git history, this might be a good feature
+for you.
+
+You can configure this on a per-project basis by navigating to the project
+settings page and selecting the **Only fast-forward merging** checkbox.
+
+![Fast forward merge in project settings](img/ff_merge.png)
+
+Now, when you visit the merge request page, you will be able to **accept it only
+if a fast-forward merge is possible**.
+
+If the target branch is ahead of the source branch, you need to rebase the
+source branch before you will be able to do a fast-forward merge.
+
+For simple rebase operations, you can use the
+[rebase before merge](rebase_before_merge.md) feature.
