+## Backporting to Release Branches
+
+We use [automated backports](https://github.com/PrismLauncher/PrismLauncher/blob/develop/.github/workflows/backport.yml) to merge specific contributions from develop into `release` branches.
+
+This is done when pull requests are merged and have labels such as `backport release-7.x` - which should be added along with the milestone for the release.
