+## Pull Requests (PRs)
+
+### How do I allow maintainers to edit my PR?
+
+When you submit a pull request, there may be additional changes
+necessary before merging it. Oftentimes, it is more efficient for the
+maintainers to make these changes themselves before merging, rather than asking you
+to do so in code review.
+
+By default, most pull requests will have a 
+`✅ Maintainers are allowed to edit this pull request.`
+badge in the right-hand sidebar.
+
+If you do not see this badge, you may have this setting off for the fork you are
+pull-requesting from. See [this Github docs page](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/allowing-changes-to-a-pull-request-branch-created-from-a-fork)
+for more information.
+
+Notably, Github doesn't allow this setting to be enabled for forks in **organizations** ([issue](https://github.com/orgs/community/discussions/5634)).
+If you are working in an organization, we recommend submitting your PR from a personal
+fork in order to enable this setting.
