+## Releases
+
+This project uses
+[release-please](https://github.com/googleapis/release-please) for automated
+release management. Releases are automatically created when changes are merged
+to the master branch following [Conventional
+Commits](https://www.conventionalcommits.org/) format. The CHANGELOG is
+automatically maintained based on commit messages.
