-## Suggest Changes
-
-> - [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/18008) in GitLab 11.6.
-> - Custom commit messages for suggestions was [introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/25381) in GitLab 13.9 behind a [feature flag](../feature_flags.md), disabled by default.
-> - [Feature flag removed](https://gitlab.com/gitlab-org/gitlab/-/issues/297404) in GitLab 13.10.
-
-As a reviewer, you're able to suggest code changes with a
-Markdown syntax in merge request diff threads. Then, the
-merge request author (or other users with appropriate
-[permission](../permissions.md)) is able to apply these
-Suggestions with a click, which generates a commit in
-the merge request authored by the user that applied them.
-
-1. Choose a line of code to be changed, add a new comment, then click
-   on the **Insert suggestion** icon in the toolbar:
-
-   ![Add a new comment](img/suggestion_button_v13_9.png)
-
-1. In the comment, add your suggestion to the pre-populated code block:
-
-   ![Add a suggestion into a code block tagged properly](img/make_suggestion_v13_9.png)
-
-1. Click either **Start a review** or **Add to review** to add your comment to a [review](#merge-request-reviews), or **Add comment now** to add the comment to the thread immediately.
-
-   The Suggestion in the comment can be applied by the merge request author
-   directly from the merge request:
-
-   ![Apply suggestions](img/apply_suggestion_v13_9.png)
-
-1. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/25381) in GitLab 13.9,
-   you can opt to add a custom commit message to describe your change. If you don't
-   specify it, the default commit message is used. It is not supported for [batch suggestions](#batch-suggestions).
-
-   ![Custom commit](img/custom_commit_v13_9.png)
-
-After the author applies a Suggestion, it is marked with the **Applied** label,
-the thread is automatically resolved, and GitLab creates a new commit
-and push the suggested change directly into the codebase in the merge request's
-branch. [Developer permission](../permissions.md) is required to do so.
-
-### Multi-line Suggestions
-
-> - [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/53310) in GitLab 11.10.
-
-Reviewers can also suggest changes to multiple lines with a single Suggestion
-within merge request diff threads by adjusting the range offsets. The
-offsets are relative to the position of the diff thread, and specify the
-range to be replaced by the suggestion when it is applied.
-
-![Multi-line suggestion syntax](img/multi-line-suggestion-syntax.png)
-
-In the example above, the Suggestion covers three lines above and four lines
-below the commented line. When applied, it would replace from 3 lines _above_
-to 4 lines _below_ the commented line, with the suggested change.
-
-![Multi-line suggestion preview](img/multi-line-suggestion-preview.png)
-
-NOTE:
-Suggestions covering multiple lines are limited to 100 lines _above_ and 100
-lines _below_ the commented diff line, allowing up to 200 changed lines per
-suggestion.
-
-### Code block nested in Suggestions
-
-If you need to make a suggestion that involves a
-[fenced code block](../markdown.md#code-spans-and-blocks), wrap your suggestion in four backticks
-instead of the usual three.
-
-![A comment editor with a suggestion with a fenced code block](img/suggestion_code_block_editor_v12_8.png)
-
-![Output of a comment with a suggestion with a fenced code block](img/suggestion_code_block_output_v12_8.png)
-
-### Configure the commit message for applied Suggestions
-
-> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/13086) in GitLab 12.7.
-
-GitLab uses a default commit message
-when applying Suggestions: `Apply %{suggestions_count} suggestion(s) to %{files_count} file(s)`
-
-For example, consider that a user applied 3 suggestions to 2 different files, the default commit message is: **Apply 3 suggestion(s) to 2 file(s)**
-
-These commit messages can be customized to follow any guidelines you might have. To do so, expand the **Merge requests**
-tab within your project's **General** settings and change the
-**Merge suggestions** text:
-
-![Custom commit message for applied Suggestions](img/suggestions_custom_commit_messages_v13_1.jpg)
-
-You can also use following variables besides static text:
-
-| Variable               | Description | Output example |
-|------------------------|-------------|----------------|
-| `%{branch_name}`       | The name of the branch the Suggestion(s) was(were) applied to. | `my-feature-branch` |
-| `%{files_count}`       | The number of file(s) to which Suggestion(s) was(were) applied.| **2** |
-| `%{file_paths}`        | The path(s) of the file(s) Suggestion(s) was(were) applied to. Paths are separated by commas.| `docs/index.md, docs/about.md` |
-| `%{project_path}`      | The project path. | `my-group/my-project` |
-| `%{project_name}`      | The human-readable name of the project. | **My Project** |
-| `%{suggestions_count}` | The number of Suggestions applied.| **3** |
-| `%{username}`          | The username of the user applying Suggestion(s). | `user_1` |
-| `%{user_full_name}`    | The full name of the user applying Suggestion(s). | **User 1** |
-
-For example, to customize the commit message to output
-**Addresses user_1's review**, set the custom text to
-`Addresses %{username}'s review`.
-
-NOTE:
-Custom commit messages for each applied Suggestion is
-introduced by [#25381](https://gitlab.com/gitlab-org/gitlab/-/issues/25381).
-
-### Batch Suggestions
-
-> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/25486) in GitLab 13.1 as an [alpha feature](https://about.gitlab.com/handbook/product/gitlab-the-product/#alpha) behind a feature flag, disabled by default.
-> - [Enabled by default](https://gitlab.com/gitlab-org/gitlab/-/issues/227799) in GitLab 13.2.
-> - [Feature flag removed](https://gitlab.com/gitlab-org/gitlab/-/issues/320755) in GitLab 13.11.
-
-You can apply multiple suggestions at once to reduce the number of commits added
-to your branch to address your reviewers' requests.
-
-1. To start a batch of suggestions to apply with a single commit, click **Add suggestion to batch**:
-
-   ![A code change suggestion displayed, with the button to add the suggestion to a batch highlighted.](img/add_first_suggestion_to_batch_v13_1.jpg "Add a suggestion to a batch")

-# Reviewing and managing merge requests **(FREE)**
+This document was moved to [another location](reviews/index.md).
 
-Merge requests are the primary method of making changes to files in a GitLab project.
-Changes are proposed by [creating and submitting a merge request](creating_merge_requests.md),
-which is then reviewed, and accepted (or rejected).
-
-## View project merge requests
-
-View all the merge requests in a project by navigating to **Project > Merge Requests**.
-
-When you access your project's merge requests, GitLab displays them in a list.
-Use the tabs to quickly filter by open and closed. You can also [search and filter the results](../../search/index.md#filtering-issue-and-merge-request-lists).
-
-![Project merge requests list view](img/project_merge_requests_list_view_v13_5.png)
-
-## View merge requests for all projects in a group
-
-View merge requests in all projects in the group, including all projects of all descendant subgroups of the group. Navigate to **Group > Merge Requests** to view these merge requests. This view also has the open and closed merge requests tabs.
-
-You can [search and filter the results](../../search/index.md#filtering-issue-and-merge-request-lists) from here.
-
-![Group Issues list view](img/group_merge_requests_list_view.png)
-
-## Cached merge request count
-
-> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/299542) in GitLab 13.11.
-> - It's [deployed behind a feature flag](../../feature_flags.md), enabled by default.
-> - It's enabled on GitLab.com.
-> - It's recommended for production use.
-> - For GitLab self-managed instances, GitLab administrators can opt to [disable it](#enable-or-disable-cached-merge-request-count).
-
-WARNING:
-This feature might not be available to you. Check the **version history** note above for details.
-
-In a group, the sidebar displays the total count of open merge requests and this value is cached if higher
-than 1000. The cached value is rounded to thousands (or millions) and updated every 24 hours.
-
-### Enable or disable cached merge request count **(FREE SELF)**
-
-Cached merge request count in the left sidebar is under development but ready for production use. It is
-deployed behind a feature flag that is **enabled by default**.
-[GitLab administrators with access to the GitLab Rails console](../../../administration/feature_flags.md)
-can disable it.
-
-To disable it:
-
-```ruby
-Feature.disable(:cached_sidebar_merge_requests_count)
-```
-
-To enable it:
-
-```ruby
-Feature.enable(:cached_sidebar_merge_requests_count)
-```
-
-## Semi-linear history merge requests
-
-A merge commit is created for every merge, but the branch is only merged if
-a fast-forward merge is possible. This ensures that if the merge request build
-succeeded, the target branch build also succeeds after the merge.
-
-Navigate to a project's settings, select the **Merge commit with semi-linear history**
-option under **Merge Requests: Merge method** and save your changes.
-
-## View changes between file versions
-
-The **Changes** tab, below the main merge request details and next to the discussion tab,
-shows the changes to files between branches or commits. This view of changes to a
-file is also known as a **diff**. By default, the diff view compares the file in the
-merge request branch and the file in the target branch.
-
-The diff view includes the following:
-
-- The file's name and path.
-- The number of lines added and deleted.
-- Buttons for the following options:
-  - Toggle comments for this file; useful for inline reviews.
-  - Edit the file in the merge request's branch.
-  - Show full file, in case you want to look at the changes in context with the rest of the file.
-  - View file at the current commit.
-  - Preview the changes with [Review Apps](../../../ci/review_apps/index.md).
-- The changed lines, with the specific changes highlighted.
-

-
-### Merge request diff file navigation
-
-When reviewing changes in the **Changes** tab the diff can be navigated using
-the file tree or file list. As you scroll through large diffs with many
-changes, you can quickly jump to any changed file using the file tree or file
-list.
-
-![Merge request diff file navigation](img/merge_request_diff_file_navigation.png)
-
-### Collapsed files in the Changes view
-
-> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/232820) in GitLab 13.4.
-
-When you review changes in the **Changes** tab, files with a large number of changes are collapsed
-to improve performance. When files are collapsed, a warning appears at the top of the changes.
-Click **Expand file** on any file to view the changes for that file.
-
-### File-by-file diff navigation
-
-> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/222790) in GitLab 13.2.
-> - [Feature flag removed](https://gitlab.com/gitlab-org/gitlab/-/issues/229848) in GitLab 13.7.
-
-For larger merge requests, consider reviewing one file at a time. To enable this feature:
-
-1. In the top-right corner, select your avatar.
-1. Select **Preferences**.
-1. Scroll to the **Behavior** section and select **Show one file at a time on merge request's Changes tab**.
-1. Select **Save changes**.
-
-After you enable this setting, GitLab displays only one file at a time in the **Changes** tab when you review merge requests. You can click **Prev** and **Next** to view other changed files.
-
-![File-by-file diff navigation](img/file_by_file_v13_2.png)
-
-In [GitLab 13.7](https://gitlab.com/gitlab-org/gitlab/-/issues/233898) and later, if you want to change
-this behavior, you can do so from your **User preferences** (as explained above) or directly in a
-merge request:
-
-1. Go to the merge request's **Changes** tab.
-1. Select the cog icon (**{settings}**) to reveal the merge request's settings dropdown.
-1. Select or deselect the checkbox **Show one file at a time** to change the setting accordingly.
-
-This change overrides the choice you made in your user preferences and persists until you clear your
-browser's cookies or change this behavior again.
-
-### Merge requests commit navigation
-
-> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/18140) in GitLab 13.0.
-
-To seamlessly navigate among commits in a merge request:
-
-1. Select the **Commits** tab.
-1. Select a commit to open it in the single-commit view.
-1. Navigate through the commits by either:
-
-   - Selecting **Prev** and **Next** buttons below the tab buttons.
-   - Using the <kbd>X</kbd> and <kbd>C</kbd> keyboard shortcuts.
-
-![Merge requests commit navigation](img/commit_nav_v13_11.png)
-
-### Incrementally expand merge request diffs
-
-By default, the diff shows only the parts of a file which are changed.
-To view more unchanged lines above or below a change click on the
-**Expand up** or **Expand down** icons. You can also click on **Show unchanged lines**
-to expand the entire file.
-
-![Incrementally expand merge request diffs](img/incrementally_expand_merge_request_diffs_v12_2.png)
-
-In GitLab [versions 13.1 and later](https://gitlab.com/gitlab-org/gitlab/-/issues/205401), when viewing a
-merge request's **Changes** tab, if a certain file was only renamed, you can expand it to see the
-entire content by clicking **Show file contents**.
-
-### Ignore whitespace changes in Merge Request diff view
-
-If you click the **Hide whitespace changes** button, you can see the diff
-without whitespace changes (if there are any). This is also working when on a
-specific commit page.
-
-![MR diff](img/merge_request_diff.png)
-
-NOTE:
-You can append `?w=1` while on the diffs page of a merge request to ignore any
-whitespace changes.
-
-## Mark files as viewed
-
-> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/51513) in GitLab 13.9.
-> - It's deployed behind a feature flag, enabled by default.
-> - It's enabled on GitLab.com.
-> - It's recommended for production use.
-> - For GitLab self-managed instances, GitLab administrators can opt to [disable it](#enable-or-disable-file-views). **(FREE SELF)**
-
-When reviewing a merge request with many files multiple times, it may be useful to the reviewer
-to focus on new changes and ignore the files that they have already reviewed and don't want to
-see anymore unless they are changed again.
-
-To mark a file as viewed:
-
-1. Go to the merge request's **Diffs** tab.
-1. On the right-top of the file, locate the **Viewed** checkbox.
-1. Check it to mark the file as viewed.
-
-Once checked, the file remains marked for that reviewer unless there are newly introduced
-changes to its content or the checkbox is unchecked.
-
-### Enable or disable file views **(FREE SELF)**
-
-The file view feature is under development but ready for production use.
-It is deployed behind a feature flag that is **enabled by default**.
-[GitLab administrators with access to the GitLab Rails console](../../../administration/feature_flags.md)
-can opt to enable it for your instance.
-
-To enable it:
-
-```ruby
-Feature.enable(:local_file_reviews)
-```
-
-To disable it:
-
-```ruby
-Feature.disable(:local_file_reviews)
-```
-
-## Perform inline code reviews
-
-> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/13950) in GitLab 11.5.
-
-In a merge request, you can leave comments in any part of the file being changed.
-In the Merge Request Diff UI, you can:
-
-- **Comment on a single line**: Click the **{comment}** **comment** icon in the
-  gutter to expand the diff lines and display a comment box.
-- [**Comment on multiple lines**](#commenting-on-multiple-lines).
-
-### Commenting on multiple lines
-
-> - [Introduced](https://gitlab.com/gitlab-org/ux-research/-/issues/870) in GitLab 13.2.
-> - [Added](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/49875) click-and-drag features in GitLab 13.8.
-> - [Feature flag removed](https://gitlab.com/gitlab-org/gitlab/-/issues/299121) in GitLab 13.9.
-
-When commenting on a diff, you can select which lines of code your comment refers
-to by either:
-
-![Comment on any diff file line](img/comment-on-any-diff-line_v13_10.png)
-
-- Clicking and dragging the **{comment}** **comment** icon in the gutter to highlight
-  lines in the diff. GitLab expands the diff lines and displays a comment box.
-- After starting a comment by clicking the **{comment}** **comment** icon in the
-  gutter, select the first line number your comment refers to in the **Commenting on lines**
-  select box. New comments default to single-line comments, unless you select
-  a different starting line.
-
-Multiline comments display the comment's line numbers above the body of the comment:
-
-![Multiline comment selection displayed above comment](img/multiline-comment-saved.png)
-
-## Pipeline status in merge requests widgets
-
-If you've set up [GitLab CI/CD](../../../ci/README.md) in your project,
-you can see:
-
-- Both pre-merge and post-merge pipelines and the environment information if any.
-- Which deployments are in progress.
-
-If an application is successfully deployed to an
-[environment](../../../ci/environments/index.md), the deployed environment and the link to the
-Review App are both shown.
-
-NOTE:
-When the pipeline fails in a merge request but it can still be merged,
-the **Merge** button is colored red.
-
-### Post-merge pipeline status
-
-When a merge request is merged, you can see the post-merge pipeline status of
-the branch the merge request was merged into. For example, when a merge request
-is merged into the [default branch](../repository/branches/default.md) and then triggers a deployment to the staging
-environment.
-
-Ongoing deployments are shown, and the state (deploying or deployed)
-for environments. If it's the first time the branch is deployed, the link
-returns a `404` error until done. During the deployment, the stop button is
-disabled. If the pipeline fails to deploy, the deployment information is hidden.
-
-![Merge request pipeline](img/merge_request_pipeline.png)
-
-For more information, [read about pipelines](../../../ci/pipelines/index.md).
-
-### Merge when pipeline succeeds (MWPS)
-
-Set a merge request that looks ready to merge to
-[merge automatically when CI pipeline succeeds](merge_when_pipeline_succeeds.md).
-
-### Live preview with Review Apps
-
-If you configured [Review Apps](https://about.gitlab.com/stages-devops-lifecycle/review-apps/) for your project,
-you can preview the changes submitted to a feature branch through a merge request
-on a per-branch basis. You don't need to checkout the branch, install, and preview locally.
-All your changes are available to preview by anyone with the Review Apps link.
-
-With GitLab [Route Maps](../../../ci/review_apps/index.md#route-maps) set, the
-merge request widget takes you directly to the pages changed, making it easier and
-faster to preview proposed modifications.
-
-[Read more about Review Apps](../../../ci/review_apps/index.md).
-

-
-## Troubleshooting
-
-Sometimes things don't go as expected in a merge request. Here are some
-troubleshooting steps.
-
-### Merge request cannot retrieve the pipeline status
-
-This can occur if Sidekiq doesn't pick up the changes fast enough.
-
-#### Sidekiq
-
-Sidekiq didn't process the CI state change fast enough. Please wait a few
-seconds and the status should update automatically.
-
-#### Bug
-
-Merge Request pipeline statuses can't be retrieved when the following occurs:
-
-1. A Merge Request is created
-1. The Merge Request is closed
-1. Changes are made in the project
-1. The Merge Request is reopened
-
-To enable the pipeline status to be properly retrieved, close and reopen the
-Merge Request again.
-
-## Tips
-
-Here are some tips to help you be more efficient with merge requests in
-the command line.
-
-### Copy the branch name for local checkout
-
-> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/23767) in GitLab 13.4.
-
-The merge request sidebar contains the branch reference for the source branch
-used to contribute changes for this merge request.
-
-To copy the branch reference into your clipboard, click the **Copy branch name** button
-(**{copy-to-clipboard}**) in the right sidebar. Use it to checkout the branch locally
-via command line by running `git checkout <branch-name>`.
-
-### Checkout merge requests locally through the `head` ref
-
-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
-ways to checkout a merge request locally.
-
-You can checkout a merge request locally even if the source
-project is a fork (even a private fork) of the target project.
-
-This relies on the merge request `head` ref (`refs/merge-requests/:iid/head`)
-that is available for each merge request. It allows checking out a merge
-request via its ID instead of its branch.
-
-[Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/223156) in GitLab
-13.4, 14 days after a merge request gets closed or merged, the merge request
-`head` ref is deleted. This means that the merge request is not available
-for local checkout via the merge request `head` ref anymore. The merge request
-can still be re-opened. If the merge request's branch
-exists, you can still check out the branch, as it isn't affected.
-
-#### Checkout locally by adding a Git alias
-
-Add the following alias to your `~/.gitconfig`:
-
-```plaintext
-[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 `origin` remote, do:
-
-```shell
-git mr origin 5
-```
-
-This fetches the merge request into a local `mr-origin-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:
-
-```plaintext
-[remote "origin"]
-  url = https://gitlab.com/gitlab-org/gitlab-foss.git
-  fetch = +refs/heads/*:refs/remotes/origin/*
-```
-
-You can open the file with:
-
-```shell
-git config -e
-```
-
-Now add the following line to the above section:
-
-```plaintext
-fetch = +refs/merge-requests/*/head:refs/remotes/origin/merge-requests/*
-```
-
-In the end, it should look like this:
-
-```plaintext
-[remote "origin"]
-  url = https://gitlab.com/gitlab-org/gitlab-foss.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:
-
-```shell
-git fetch origin
-
-...
-From https://gitlab.com/gitlab-org/gitlab-foss.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:
-
-```shell
-git checkout origin/merge-requests/1
-```
-
-All the above can be done with the [`git-mr`](https://gitlab.com/glensc/git-mr) script.

+
+# Reviewing and managing merge requests **(FREE)**
+
+Merge requests are the primary method of making changes to files in a GitLab project.
+Changes are proposed by [creating and submitting a merge request](../creating_merge_requests.md),
+which is then reviewed, and accepted (or rejected).
+
+## View project merge requests
+
+View all the merge requests in a project by navigating to **Project > Merge Requests**.
+
+When you access your project's merge requests, GitLab displays them in a list.
+Use the tabs to quickly filter by open and closed. You can also [search and filter the results](../../../search/index.md#filtering-issue-and-merge-request-lists).
+
+![Project merge requests list view](img/project_merge_requests_list_view_v13_5.png)
+
+## View merge requests for all projects in a group
+
+View merge requests in all projects in the group, including all projects of all descendant subgroups of the group. Navigate to **Group > Merge Requests** to view these merge requests. This view also has the open and closed merge requests tabs.
+
+You can [search and filter the results](../../../search/index.md#filtering-issue-and-merge-request-lists) from here.
+
+![Group Issues list view](img/group_merge_requests_list_view.png)
+
+## Cached merge request count
+
+> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/299542) in GitLab 13.11.
+> - It's [deployed behind a feature flag](../../../feature_flags.md), enabled by default.
+> - It's enabled on GitLab.com.
+> - It's recommended for production use.
+> - For GitLab self-managed instances, GitLab administrators can opt to [disable it](#enable-or-disable-cached-merge-request-count).
+
+WARNING:
+This feature might not be available to you. Check the **version history** note above for details.
+
+In a group, the sidebar displays the total count of open merge requests and this value is cached if higher
+than 1000. The cached value is rounded to thousands (or millions) and updated every 24 hours.
+
+### Enable or disable cached merge request count **(FREE SELF)**
+
+Cached merge request count in the left sidebar is under development but ready for production use. It is
+deployed behind a feature flag that is **enabled by default**.
+[GitLab administrators with access to the GitLab Rails console](../../../../administration/feature_flags.md)
+can disable it.
+
+To disable it:
+
+```ruby
+Feature.disable(:cached_sidebar_merge_requests_count)
+```
+
+To enable it:
+
+```ruby
+Feature.enable(:cached_sidebar_merge_requests_count)
+```
+
+## Semi-linear history merge requests
+
+A merge commit is created for every merge, but the branch is only merged if
+a fast-forward merge is possible. This ensures that if the merge request build
+succeeded, the target branch build also succeeds after the merge.
+
+Navigate to a project's settings, select the **Merge commit with semi-linear history**
+option under **Merge Requests: Merge method** and save your changes.
+
+## View changes between file versions
+
+The **Changes** tab, below the main merge request details and next to the discussion tab,
+shows the changes to files between branches or commits. This view of changes to a
+file is also known as a **diff**. By default, the diff view compares the file in the
+merge request branch and the file in the target branch.
+
+The diff view includes the following:
+
+- The file's name and path.
+- The number of lines added and deleted.
+- Buttons for the following options:
+  - Toggle comments for this file; useful for inline reviews.
+  - Edit the file in the merge request's branch.
+  - Show full file, in case you want to look at the changes in context with the rest of the file.
+  - View file at the current commit.
+  - Preview the changes with [Review Apps](../../../../ci/review_apps/index.md).
+- The changed lines, with the specific changes highlighted.
+
+![Example screenshot of a source code diff](img/merge_request_diff_v12_2.png)
+
+### Merge request diff file navigation
+
+When reviewing changes in the **Changes** tab the diff can be navigated using
+the file tree or file list. As you scroll through large diffs with many
+changes, you can quickly jump to any changed file using the file tree or file
+list.
+
+![Merge request diff file navigation](img/merge_request_diff_file_navigation.png)
+
+### Collapsed files in the Changes view
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/232820) in GitLab 13.4.
+
+When you review changes in the **Changes** tab, files with a large number of changes are collapsed
+to improve performance. When files are collapsed, a warning appears at the top of the changes.
+Click **Expand file** on any file to view the changes for that file.
+
+### File-by-file diff navigation
+
+> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/222790) in GitLab 13.2.
+> - [Feature flag removed](https://gitlab.com/gitlab-org/gitlab/-/issues/229848) in GitLab 13.7.
+
+For larger merge requests, consider reviewing one file at a time. To enable this feature:
+
+1. In the top-right corner, select your avatar.
+1. Select **Preferences**.
+1. Scroll to the **Behavior** section and select **Show one file at a time on merge request's Changes tab**.
+1. Select **Save changes**.
+
+After you enable this setting, GitLab displays only one file at a time in the **Changes** tab when you review merge requests. You can click **Prev** and **Next** to view other changed files.
+
+![File-by-file diff navigation](img/file_by_file_v13_2.png)
+
+In [GitLab 13.7](https://gitlab.com/gitlab-org/gitlab/-/issues/233898) and later, if you want to change
+this behavior, you can do so from your **User preferences** (as explained above) or directly in a
+merge request:
+
+1. Go to the merge request's **Changes** tab.
+1. Select the cog icon (**{settings}**) to reveal the merge request's settings dropdown.
+1. Select or deselect the checkbox **Show one file at a time** to change the setting accordingly.
+
+This change overrides the choice you made in your user preferences and persists until you clear your
+browser's cookies or change this behavior again.
+
+### Merge requests commit navigation
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/18140) in GitLab 13.0.
+
+To seamlessly navigate among commits in a merge request:
+
+1. Select the **Commits** tab.
+1. Select a commit to open it in the single-commit view.
+1. Navigate through the commits by either:
+
+   - Selecting **Prev** and **Next** buttons below the tab buttons.
+   - Using the <kbd>X</kbd> and <kbd>C</kbd> keyboard shortcuts.
+
+![Merge requests commit navigation](img/commit_nav_v13_11.png)
+
+### Incrementally expand merge request diffs
+
+By default, the diff shows only the parts of a file which are changed.
+To view more unchanged lines above or below a change click on the
+**Expand up** or **Expand down** icons. You can also click on **Show unchanged lines**
+to expand the entire file.
+
+![Incrementally expand merge request diffs](img/incrementally_expand_merge_request_diffs_v12_2.png)
+
+In GitLab [versions 13.1 and later](https://gitlab.com/gitlab-org/gitlab/-/issues/205401), when viewing a
+merge request's **Changes** tab, if a certain file was only renamed, you can expand it to see the
+entire content by clicking **Show file contents**.
+
+### Ignore whitespace changes in Merge Request diff view
+
+If you click the **Hide whitespace changes** button, you can see the diff
+without whitespace changes (if there are any). This is also working when on a
+specific commit page.
+
+![MR diff](img/merge_request_diff.png)
+
+NOTE:
+You can append `?w=1` while on the diffs page of a merge request to ignore any
+whitespace changes.
+
+## Mark files as viewed
+
+> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/51513) in GitLab 13.9.
+> - It's deployed behind a feature flag, enabled by default.
+> - It's enabled on GitLab.com.
+> - It's recommended for production use.
+> - For GitLab self-managed instances, GitLab administrators can opt to [disable it](#enable-or-disable-file-views). **(FREE SELF)**
+
+When reviewing a merge request with many files multiple times, it may be useful to the reviewer
+to focus on new changes and ignore the files that they have already reviewed and don't want to
+see anymore unless they are changed again.
+
+To mark a file as viewed:
+
+1. Go to the merge request's **Diffs** tab.
+1. On the right-top of the file, locate the **Viewed** checkbox.
+1. Check it to mark the file as viewed.
+
+Once checked, the file remains marked for that reviewer unless there are newly introduced
+changes to its content or the checkbox is unchecked.
+
+### Enable or disable file views **(FREE SELF)**
+
+The file view feature is under development but ready for production use.
+It is deployed behind a feature flag that is **enabled by default**.
+[GitLab administrators with access to the GitLab Rails console](../../../../administration/feature_flags.md)
+can opt to enable it for your instance.
+
+To enable it:
+
+```ruby
+Feature.enable(:local_file_reviews)
+```
+
+To disable it:
+
+```ruby
+Feature.disable(:local_file_reviews)
+```
+
+## Perform inline code reviews
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/13950) in GitLab 11.5.
+
+In a merge request, you can leave comments in any part of the file being changed.
+In the Merge Request Diff UI, you can:
+
+- **Comment on a single line**: Click the **{comment}** **comment** icon in the
+  gutter to expand the diff lines and display a comment box.
+- [**Comment on multiple lines**](#commenting-on-multiple-lines).
+
+### Commenting on multiple lines
+
+> - [Introduced](https://gitlab.com/gitlab-org/ux-research/-/issues/870) in GitLab 13.2.
+> - [Added](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/49875) click-and-drag features in GitLab 13.8.
+> - [Feature flag removed](https://gitlab.com/gitlab-org/gitlab/-/issues/299121) in GitLab 13.9.
+
+When commenting on a diff, you can select which lines of code your comment refers
+to by either:
+
+![Comment on any diff file line](img/comment-on-any-diff-line_v13_10.png)
+
+- Clicking and dragging the **{comment}** **comment** icon in the gutter to highlight
+  lines in the diff. GitLab expands the diff lines and displays a comment box.
+- After starting a comment by clicking the **{comment}** **comment** icon in the
+  gutter, select the first line number your comment refers to in the **Commenting on lines**
+  select box. New comments default to single-line comments, unless you select
+  a different starting line.
+
+Multiline comments display the comment's line numbers above the body of the comment:
+
+![Multiline comment selection displayed above comment](img/multiline-comment-saved.png)
+
+## Pipeline status in merge requests widgets
+
+If you've set up [GitLab CI/CD](../../../../ci/README.md) in your project,
+you can see:
+
+- Both pre-merge and post-merge pipelines and the environment information if any.
+- Which deployments are in progress.
+
+If an application is successfully deployed to an
+[environment](../../../../ci/environments/index.md), the deployed environment and the link to the
+Review App are both shown.
+
+NOTE:
+When the pipeline fails in a merge request but it can still be merged,
+the **Merge** button is colored red.
+
+### Post-merge pipeline status
+
+When a merge request is merged, you can see the post-merge pipeline status of
+the branch the merge request was merged into. For example, when a merge request
+is merged into the [default branch](../../repository/branches/default.md) and then triggers a deployment to the staging
+environment.
+
+Ongoing deployments are shown, and the state (deploying or deployed)
+for environments. If it's the first time the branch is deployed, the link
+returns a `404` error until done. During the deployment, the stop button is
+disabled. If the pipeline fails to deploy, the deployment information is hidden.
+
+![Merge request pipeline](img/merge_request_pipeline.png)
+
+For more information, [read about pipelines](../../../../ci/pipelines/index.md).
+
+### Merge when pipeline succeeds (MWPS)
+
+Set a merge request that looks ready to merge to
+[merge automatically when CI pipeline succeeds](../merge_when_pipeline_succeeds.md).
+
+### Live preview with Review Apps
+
+If you configured [Review Apps](https://about.gitlab.com/stages-devops-lifecycle/review-apps/) for your project,
+you can preview the changes submitted to a feature branch through a merge request
+on a per-branch basis. You don't need to checkout the branch, install, and preview locally.
+All your changes are available to preview by anyone with the Review Apps link.
+
+With GitLab [Route Maps](../../../../ci/review_apps/index.md#route-maps) set, the
+merge request widget takes you directly to the pages changed, making it easier and
+faster to preview proposed modifications.
+
+[Read more about Review Apps](../../../../ci/review_apps/index.md).
+

+
+## Troubleshooting
+
+Sometimes things don't go as expected in a merge request. Here are some
+troubleshooting steps.
+
+### Merge request cannot retrieve the pipeline status
+
+This can occur if Sidekiq doesn't pick up the changes fast enough.
+
+#### Sidekiq
+
+Sidekiq didn't process the CI state change fast enough. Please wait a few
+seconds and the status should update automatically.
+
+#### Bug
+
+Merge Request pipeline statuses can't be retrieved when the following occurs:
+
+1. A Merge Request is created
+1. The Merge Request is closed
+1. Changes are made in the project
+1. The Merge Request is reopened
+
+To enable the pipeline status to be properly retrieved, close and reopen the
+Merge Request again.
+
+## Tips
+
+Here are some tips to help you be more efficient with merge requests in
+the command line.
+
+### Copy the branch name for local checkout
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/23767) in GitLab 13.4.
+
+The merge request sidebar contains the branch reference for the source branch
+used to contribute changes for this merge request.
+
+To copy the branch reference into your clipboard, click the **Copy branch name** button
+(**{copy-to-clipboard}**) in the right sidebar. Use it to checkout the branch locally
+via command line by running `git checkout <branch-name>`.
+
+### Checkout merge requests locally through the `head` ref
+
+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
+ways to checkout a merge request locally.
+
+You can checkout a merge request locally even if the source
+project is a fork (even a private fork) of the target project.
+
+This relies on the merge request `head` ref (`refs/merge-requests/:iid/head`)
+that is available for each merge request. It allows checking out a merge
+request via its ID instead of its branch.
+
+[Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/223156) in GitLab
+13.4, 14 days after a merge request gets closed or merged, the merge request
+`head` ref is deleted. This means that the merge request is not available
+for local checkout via the merge request `head` ref anymore. The merge request
+can still be re-opened. If the merge request's branch
+exists, you can still check out the branch, as it isn't affected.
+
+#### Checkout locally by adding a Git alias
+
+Add the following alias to your `~/.gitconfig`:
+
+```plaintext
+[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 `origin` remote, do:
+
+```shell
+git mr origin 5
+```
+
+This fetches the merge request into a local `mr-origin-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:
+
+```plaintext
+[remote "origin"]
+  url = https://gitlab.com/gitlab-org/gitlab-foss.git
+  fetch = +refs/heads/*:refs/remotes/origin/*
+```
+
+You can open the file with:
+
+```shell
+git config -e
+```
+
+Now add the following line to the above section:
+
+```plaintext
+fetch = +refs/merge-requests/*/head:refs/remotes/origin/merge-requests/*
+```
+
+In the end, it should look like this:
+
+```plaintext
+[remote "origin"]
+  url = https://gitlab.com/gitlab-org/gitlab-foss.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:
+
+```shell
+git fetch origin
+
+...
+From https://gitlab.com/gitlab-org/gitlab-foss.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:
+
+```shell
+git checkout origin/merge-requests/1
+```
+
+All the above can be done with the [`git-mr`](https://gitlab.com/glensc/git-mr) script.

+> - [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/18008) in GitLab 11.6.
+> - Custom commit messages for suggestions was [introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/25381) in GitLab 13.9 behind a [feature flag](../../../feature_flags.md), disabled by default.
+> - [Feature flag removed](https://gitlab.com/gitlab-org/gitlab/-/issues/297404) in GitLab 13.10.
+
+As a reviewer, you're able to suggest code changes with a
+Markdown syntax in merge request diff threads. Then, the
+merge request author (or other users with appropriate
+[permission](../../../permissions.md)) is able to apply these
+Suggestions with a click, which generates a commit in
+the merge request authored by the user that applied them.
+
+1. Choose a line of code to be changed, add a new comment, then click
+   on the **Insert suggestion** icon in the toolbar:
+
+   ![Add a new comment](img/suggestion_button_v13_9.png)
+
+1. In the comment, add your suggestion to the pre-populated code block:
+
+   ![Add a suggestion into a code block tagged properly](img/make_suggestion_v13_9.png)
+
+1. Click either **Start a review** or **Add to review** to add your comment to a [review](index.md), or **Add comment now** to add the comment to the thread immediately.
+
+   The Suggestion in the comment can be applied by the merge request author
+   directly from the merge request:
+
+   ![Apply suggestions](img/apply_suggestion_v13_9.png)
+
+1. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/25381) in GitLab 13.9,
+   you can opt to add a custom commit message to describe your change. If you don't
+   specify it, the default commit message is used. It is not supported for [batch suggestions](#batch-suggestions).
+
+   ![Custom commit](img/custom_commit_v13_9.png)
+
+After the author applies a Suggestion, it is marked with the **Applied** label,
+the thread is automatically resolved, and GitLab creates a new commit
+and push the suggested change directly into the codebase in the merge request's
+branch. [Developer permission](../../../permissions.md) is required to do so.
+
+## Multi-line Suggestions
+
+> - [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/53310) in GitLab 11.10.
+
+Reviewers can also suggest changes to multiple lines with a single Suggestion
+within merge request diff threads by adjusting the range offsets. The
+offsets are relative to the position of the diff thread, and specify the
+range to be replaced by the suggestion when it is applied.
+
+![Multi-line suggestion syntax](img/multi-line-suggestion-syntax.png)
+
+In the example above, the Suggestion covers three lines above and four lines
+below the commented line. When applied, it would replace from 3 lines _above_
+to 4 lines _below_ the commented line, with the suggested change.
+
+![Multi-line suggestion preview](img/multi-line-suggestion-preview.png)
+
+NOTE:
+Suggestions covering multiple lines are limited to 100 lines _above_ and 100
+lines _below_ the commented diff line, allowing up to 200 changed lines per
+suggestion.
+
+## Code block nested in Suggestions
+
+If you need to make a suggestion that involves a
+[fenced code block](../../../markdown.md#code-spans-and-blocks), wrap your suggestion in four backticks
+instead of the usual three.
+
+![A comment editor with a suggestion with a fenced code block](img/suggestion_code_block_editor_v12_8.png)
+

+
+## Configure the commit message for applied Suggestions
+
+> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/13086) in GitLab 12.7.
+
+GitLab uses a default commit message
+when applying Suggestions: `Apply %{suggestions_count} suggestion(s) to %{files_count} file(s)`
+
+For example, consider that a user applied 3 suggestions to 2 different files, the default commit message is: **Apply 3 suggestion(s) to 2 file(s)**
+
+These commit messages can be customized to follow any guidelines you might have. To do so, expand the **Merge requests**
+tab within your project's **General** settings and change the
+**Merge suggestions** text:
+
+![Custom commit message for applied Suggestions](img/suggestions_custom_commit_messages_v13_1.jpg)
+
+You can also use following variables besides static text:
+
+| Variable               | Description | Output example |
+|------------------------|-------------|----------------|
+| `%{branch_name}`       | The name of the branch the Suggestion(s) was(were) applied to. | `my-feature-branch` |
+| `%{files_count}`       | The number of file(s) to which Suggestion(s) was(were) applied.| **2** |
+| `%{file_paths}`        | The path(s) of the file(s) Suggestion(s) was(were) applied to. Paths are separated by commas.| `docs/index.md, docs/about.md` |
+| `%{project_path}`      | The project path. | `my-group/my-project` |
+| `%{project_name}`      | The human-readable name of the project. | **My Project** |
+| `%{suggestions_count}` | The number of Suggestions applied.| **3** |
+| `%{username}`          | The username of the user applying Suggestion(s). | `user_1` |
+| `%{user_full_name}`    | The full name of the user applying Suggestion(s). | **User 1** |
+
+For example, to customize the commit message to output
+**Addresses user_1's review**, set the custom text to
+`Addresses %{username}'s review`.
+
+NOTE:
+Custom commit messages for each applied Suggestion is
+introduced by [#25381](https://gitlab.com/gitlab-org/gitlab/-/issues/25381).
+
+## Batch Suggestions
+
+> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/25486) in GitLab 13.1 as an [alpha feature](https://about.gitlab.com/handbook/product/gitlab-the-product/#alpha) behind a feature flag, disabled by default.
+> - [Enabled by default](https://gitlab.com/gitlab-org/gitlab/-/issues/227799) in GitLab 13.2.
+> - [Feature flag removed](https://gitlab.com/gitlab-org/gitlab/-/issues/320755) in GitLab 13.11.
+
+You can apply multiple suggestions at once to reduce the number of commits added
+to your branch to address your reviewers' requests.
+
+1. To start a batch of suggestions to apply with a single commit, click **Add suggestion to batch**:
+
+   ![A code change suggestion displayed, with the button to add the suggestion to a batch highlighted.](img/add_first_suggestion_to_batch_v13_1.jpg "Add a suggestion to a batch")
+
+1. Add as many additional suggestions to the batch as you wish:
+
+   ![A code change suggestion displayed, with the button to add an additional suggestion to a batch highlighted.](img/add_another_suggestion_to_batch_v13_1.jpg "Add another suggestion to a batch")
+
+1. To remove suggestions, click **Remove from batch**:
+
+   ![A code change suggestion displayed, with the button to remove that suggestion from its batch highlighted.](img/remove_suggestion_from_batch_v13_1.jpg "Remove a suggestion from a batch")
+
+1. Having added all the suggestions to your liking, when ready, click **Apply suggestions**:
+
+   ![A code change suggestion displayed, with the button to apply the batch of suggestions highlighted.](img/apply_batch_of_suggestions_v13_1.jpg "Apply a batch of suggestions")
+
+WARNING:
+Suggestions applied from multiple authors creates a commit authored by the user applying the suggestions.
