+## Add a redirect
 
 NOTE:
-If the old page you're renaming doesn't exist in a stable branch, skip the
-following steps and ask a Technical Writer to add the redirect in
-[`redirects.yaml`](https://gitlab.com/gitlab-org/gitlab-docs/-/blob/main/content/_data/redirects.yaml).
-For example, if you add a new page on the 3rd of the month and then rename it before it gets
-added in the stable branch on the 18th, the old page will never be part of the internal `/help`.
-In that case, you can jump straight to the
-[Pages redirect](https://gitlab.com/gitlab-org/gitlab-docs/-/blob/main/doc/maintenance.md#pages-redirects).
+If the renamed page is new, you can sometimes skip the following steps and ask a
+Technical Writer to manually add the redirect to [`redirects.yaml`](https://gitlab.com/gitlab-org/gitlab-docs/-/blob/main/content/_data/redirects.yaml).
+For example, if you add a new page and then rename it before it's added to a release
+on the 18th. The old page is not in any version's `/help` section, so a technical writer
+can jump straight to the [Pages redirect](https://gitlab.com/gitlab-org/gitlab-docs/-/blob/main/doc/maintenance.md#pages-redirects).
