-file.
-
-To add a redirect:
-
-1. In the repository (`gitlab`, `gitlab-runner`, `omnibus-gitlab`, or `charts`),
-   create a new documentation file. Don't delete the old one. The easiest
-   way is to copy it. For example:
-
-   ```shell
-   cp doc/user/search/old_file.md doc/api/new_file.md
-   ```
-
-1. Add the redirect code to the old documentation file by running the
-   following Rake task. The first argument is the path of the old file,
-   and the second argument is the path of the new file:
-
-   - To redirect to a page in the same project, use relative paths and
-     the `.md` extension. Both old and new paths start from the same location.
-     In the following example, both paths are relative to `doc/`:
-
-     ```shell
-     bundle exec rake "gitlab:docs:redirect[doc/user/search/old_file.md, doc/api/new_file.md]"
-     ```
-
-   - To redirect to a page in a different project or site, use the full URL (with `https://`) :
-
-     ```shell
-     bundle exec rake "gitlab:docs:redirect[doc/user/search/old_file.md, https://example.com]"
-     ```
-
-   Alternatively, you can omit the arguments and be asked to enter their values:
-
-   ```shell
-   bundle exec rake gitlab:docs:redirect
-   ```
-
-   If you don't want to use the Rake task, you can use the following template.
-   However, the file paths must be relative to the `doc` or `docs` directory.
-
-   Replace the value of `redirect_to` with the new file path and `YYYY-MM-DD`
-   with the date the file should be removed.
-
-   Redirect files that link to docs in internal documentation projects
-   are removed after three months. Redirect files that link to external sites are
-   removed after one year:
-
-   ```markdown
-   ---
-   redirect_to: '../newpath/to/file/index.md'
-   remove_date: 'YYYY-MM-DD'
-   ---
-
-   This document was moved to [another location](../path/to/file/index.md).
-
-   <!-- This redirect file can be deleted after <YYYY-MM-DD>. -->
-   <!-- Before deletion, see: https://docs.gitlab.com/ee/development/documentation/#move-or-rename-a-page -->
-   ```
-
-1. If the documentation page being moved has any Disqus comments, follow the steps
-   described in [Redirections for pages with Disqus comments](#redirections-for-pages-with-disqus-comments).
-1. Open a merge request with your changes. If a documentation page
-   you're removing includes images that aren't used
-   with any other documentation pages, be sure to use your merge request to delete
-   those images from the repository.
-1. Assign the merge request to a technical writer for review and merge.
-1. Search for links to the old documentation file. You must find and update all
-   links that point to the old documentation file:
-
-   - In <https://gitlab.com/gitlab-com/www-gitlab-com>, search for full URLs:
-     `grep -r "docs.gitlab.com/ee/path/to/file.html" .`
-   - In <https://gitlab.com/gitlab-org/gitlab-docs/-/tree/master/content/_data>,
-     search the navigation bar configuration files for the path with `.html`:
-     `grep -r "path/to/file.html" .`
-   - In any of the four internal projects, search for links in the docs
-     and codebase. Search for all variations, including full URL and just the path.
-     For example, go to the root directory of the `gitlab` project and run:
-
-     ```shell
-     grep -r "docs.gitlab.com/ee/path/to/file.html" .
-     grep -r "path/to/file.html" .
-     grep -r "path/to/file.md" .
-     grep -r "path/to/file" .
