+-------------------------------------
+
+The following script will rebase the commits that need to be backported onto
+this backport branch. Resolve any conflicts as you normally would in a rebase.
+You do *not* need to remove these backport.rej files, and you can add
+additional commits if that's necessary.
+
+```
+sh begin-backport.rej
+```
+
+Once the conficts are resolved on your local backport branch, the following
+script will remove the remnants of this backport commit and squash the newly
+resolved commits (and any others you may have added) into a single backport
+commit with the proper commit message. Finally, it'll replace the upstream
+backport branch (the one from the backport PR) with the result.
+
+```
+sh finish-backport.rej
