-Every time a new release is created, the CI/CD pipeline will execute and a new artifact will be released on Maven Central. **The pipeline updates the version automatically!**
-If you ever change the OSSRH login credentials, you'll need to also update the repository variables on Github.
 
+Publishing to Maven Central is done via the **GitHub Actions `publish` workflow**, triggered **manually per tag**. It does not run automatically on release creation.
+
+1. **Version the project** and create a **git tag** (e.g. `v1.1.6`), then push the tag.
