 # Git rebase and force push **(FREE ALL)**
 
-This guide helps you to get started with rebases, force pushes, and fixing
-[merge conflicts](../../user/project/merge_requests/conflicts.md) locally.
-Before you attempt a force push or a rebase, make sure you are familiar with
-[Git through the command line](../../gitlab-basics/start-using-git.md).
+In Git, a rebase updates your branch with the contents of another branch.
+A rebase confirms that changes in your branch don't conflict with
+changes in the target branch.
 
-WARNING:
-`git rebase` rewrites the commit history. It **can be harmful** to do it in
-shared branches. It can cause complex and hard to resolve
-[merge conflicts](../../user/project/merge_requests/conflicts.md). In
-these cases, instead of rebasing your branch against the default branch,

 While most rebases are performed against `main`, you can rebase against any other
 branch, such as `release-15-3`. You can also specify a different remote repository
 (such as `upstream`) instead of `origin`.
 
-## Back up a branch before rebase
+WARNING:
+`git rebase` rewrites the commit history. It **can be harmful** to do it in
+shared branches. It can cause complex and hard to resolve
+merge conflicts. Instead of rebasing your branch against the default branch,
+consider pulling it instead (`git pull origin master`). Pulling has similar
+effects with less risk of compromising others' work.
 
-To back up a branch before taking any destructive action, like a rebase or force push:
+## Rebase by using Git
 
-1. Open your feature branch in the terminal: `git checkout my-feature`
-1. Create a backup branch: `git branch my-feature-backup`
-   Any changes added to `my-feature` after this point are lost
-   if you restore from the backup branch.
+When you use Git to rebase, each commit is applied to your branch.
+When merge conflicts occur, you are prompted to address them.
 
-Your branch is backed up, and you can try a rebase or a force push.
-If anything goes wrong, restore your branch from its backup:
-
-1. Make sure you're in the correct branch (`my-feature`): `git checkout my-feature`
-1. Reset it against `my-feature-backup`: `git reset --hard my-feature-backup`
-
-## Rebase a branch
-
-[Rebases](https://git-scm.com/docs/git-rebase) are very common operations in
-Git, and have these options:
-
-- **Regular rebases.** This type of rebase can be done through the
-  [command line](#regular-rebase) and [the GitLab UI](#from-the-gitlab-ui).
-- [**Interactive rebases**](#interactive-rebase) give more flexibility by
-  enabling you to specify how to handle each commit. Interactive rebases
-  must be done on the command line.
-
-Any user who rebases a branch is treated as having added commits to that branch.
-If a project is configured to
-[**prevent approvals by users who add commits**](../../user/project/merge_requests/approvals/settings.md#prevent-approvals-by-users-who-add-commits),
-a user who rebases a branch cannot also approve its merge request.
-
-### Regular rebase
-
-Standard rebases replay the previous commits on a branch without changes, stopping
-only if merge conflicts occur.
+If you want more advanced options for your commits,
+do [an interactive rebase](#rebase-interactively-by-using-git).

+1. Open these commits. For example, to edit the last five commits in your branch (`HEAD~5`), type:
+
+   ```shell
+   git rebase -i HEAD~5
+   ```
+
+   Git opens the last five commits in your terminal text editor, oldest commit first.

+
+## Force pushing
 
 Complex operations in Git require you to force an update to the remote branch.
 Operations like squashing commits, resetting a branch, or rebasing a branch rewrite
 the history of your branch. Git requires a forced update to help safeguard against
 these more destructive changes from happening accidentally.

+## Custom merge drivers
+
+> Ability to configure custom merge drivers through GitLab introduced in GitLab 15.10.
+
+You can define [custom merge drivers](https://git-scm.com/docs/gitattributes#_defining_a_custom_merge_driver)
+in a GitLab configuration file, then use the custom merge drivers in a Git
+`.gitattributes` file.
+
+You might configure a custom merge driver, for example, if there are certain
+files that should be ignored during a merge such as build files and configuration files.
+
+### Configure a custom merge driver
+
+The following example illustrates how to define and use a custom merge driver in
+GitLab.
+
+How to configure a custom merge driver depends on the type of installation.
+
+::Tabs
+
+:::TabTitle Linux package (Omnibus)
+
+1. Edit `/etc/gitlab/gitlab.rb`.
+1. Add configuration similar to the following:
+
+   ```ruby
+   gitaly['configuration'] = {
+     # ...
+     git: {
+       # ...
+       config: [
+         # ...
+         { key: "merge.foo.driver", value: "true" },
+       ],
+     },
+   }
+   ```
+
+:::TabTitle Self-compiled (source)
+
+1. Edit `gitaly.toml`.
+1. Add configuration similar to the following:
+
+   ```toml
+   [[git.config]]
+   key = "merge.foo.driver"
+   value = "true"
+   ```
+
+::EndTabs
+
+In this example, during a merge, Git uses the `driver` value as the command to execute. In
+this case, because we are using [`true`](https://man7.org/linux/man-pages/man1/true.1.html)
+with no arguments, it always returns a non-zero return code. This means that for
+the files specified in `.gitattributes`, merges do nothing.
+
+To use your own merge driver, replace the value in `driver` to point to an
+executable. For more details on how this command is invoked, please see the Git
+documentation on [custom merge drivers](https://git-scm.com/docs/gitattributes#_defining_a_custom_merge_driver).
+
+### Use `.gitattributes` to set files custom merge driver applies to
+
+In a `.gitattributes` file, you can set the paths of files you want to use with the custom merge driver. For example:
+
+```plaintext
+config/* merge=foo
+```
+
+In this case, every file under the `config/` folder uses the custom merge driver called `foo` defined in the GitLab configuration.
