+## Release Workflow
+
+There are multiple GitHub Action Workflows for the different steps in the package's lifecycle:
+
+- CI: Builds and checks incoming changes on a pull request
+    - triggered on every push to a non-default branch
+- CD: Publishes the Gradle artifacts to GitHub Package Registry
+    - triggered only on pushes to the default branch
+- Release: Publishes Gradle artifacts to Sonatype and releases them to Maven Central
+    - triggered on a published GitHub release using the underlying tag as artifact version, e.g. via `git tag -m "$MESSAGE" v$(date +"%Y-%m-%dT%H-%M-%S")`
+
