+## Releasing the Plugin
+
+The release process of the plugin is automated using Github Actions.
+On each push to the `main` branch, a new prerelease is created and the corresponding commit is tagged "latest".
+Old prereleases will be deleted.
+
+To create a normal release, the commit that is used as the basis for the release must be tagged with the following format: `v*.*.*`.
+After that, the release is built and created with the version number extracted from the tag.
+Furthermore, a new commit is created, which sets the current version in the `main` branch to the version that has been released.
