 4. **Run the "Prepare Release" Workflow**
     - After the PR is merged, trigger the "Prepare Release" workflow (using Maven Release Plugin) to prepare the release.
+    - Enter the release version (e.g., `2.0.0`, `2.0.0-M1`, or `2.0.0-RC1`) and the next development version.
     - This will update versions, tag the release, and push changes to the repository.
+    - **For Milestones and RCs**: The tag will trigger the release workflow automatically. After publishing to Maven Central, mark the GitHub release as "Pre-release".
 
 5. **Publish Artifacts to Maven Central**
     - Once the workflow completes successfully, go to Maven Central and publish the release from the service account.
