+### Release process
+
+To create a new minor or patch release:
+
+- push the new tag to the main branch
+
+- create a new GitHub release with a description of the changes in this release
+
+- repush the latest major release tag to point at the new latest release.

+This approach follows the [official GitHub actions versioning guidelines](https://docs.github.com/en/actions/creating-actions/about-custom-actions#using-tags-for-release-management).
