+## What to do if you are pinged in a `CE Upstream` merge request to resolve a conflict?
+
+1. Please resolve the conflict as soon as possible or ask someone else to do it
+  - It's ok to resolve more conflicts than the one that you are asked to resolve.
+    In that case, it's a good habit to ask for a double-check on your resolution
+    by someone who is familiar with the code you touched.
+1. Once you have resolved your conflicts, push to the branch (no force-push)
+1. Assign the merge request to the next person that has to resolve a conflict
+1. If all conflicts are resolved after your resolution is pushed, keep the merge
+  request assigned to you: **you are now responsible for the merge request to be
+  green**
+1. If you need any help, you can ping the current [release managers], or ask in
+  the `#ce-to-ee` Slack channel
+
+A few notes about the automatic CE->EE merge job:
+
+- If a merge is already in progress, the job
+  [doesn't create a new one](https://gitlab.com/gitlab-org/release-tools/-/jobs/43157687).
+- If there is nothing to merge (i.e. EE is up-to-date with CE), the job doesn't
+  create a new one
+- The job posts messages to the `#ce-to-ee` Slack channel to inform what's the
+  current CE->EE merge status (e.g. "A new MR has been created", "A MR is still pending")
