 ------------------------------------
 
 Pull requests can be accepted and merged by a Python Core Developer.
+You can read more about what to look for before accepting a change
+:ref:`here <committing>`.
 
-1. At the bottom of the pull request page, click the ``Squash and merge``
-   button.
+All pull requests have required checks that need to pass before a change
+can be merged. After a change was accepted by at least one core
+developer review, you can schedule an automatic merge of the change by
+clicking the gray ``Enable auto-merge (squash)`` button. You will find
+it at the bottom of the pull request page. The auto-merge will only
+happen if all the required checks pass.
 
-2. Replace the reference to GitHub pull request ``#NNNN`` with ``GH-NNNN``.
-   If the title is too long, the pull request number can be added to the
-   message body.
+If all required checks are already finished on a PR you're reviewing,
+in place of the gray ``Enable auto-merge`` button you will find a green
+``Squash and merge`` button.

+
+Cancelling an Automatic Merge
+-----------------------------
+
+If you notice a problem with a pull request that was accepted and where
+auto-merge was enabled, you can still cancel the workflow before GitHub
+automatically merges the change.
+
+Press the gray "Disable auto-merge" button on the bottom of the
+pull request page to disable automatic merging entirely. This is the
+recommended approach.
+
+To pause automatic merging, apply the "DO-NOT-MERGE" label to the PR or
+submit a review requesting changes. The latter will put an "awaiting
+changes" label on the PR, which pauses the auto-merge similarly to
+"DO-NOT-MERGE". After the author submits a fix, re-requests review, and
+receives a new accepting review, auto-merge will complete.
+
+Note that pushing new changes after the auto-merge flow was enabled
+does **NOT** stop it.
