+
+The Guided Exploration project [Utterly Automated Software and Artifact Versioning with GitVersion](https://gitlab.com/guided-explorations/devops-patterns/utterly-automated-versioning) demonstrates:
+
+- Using GitLab releases.
+- Using the GitLab `release-cli`.
+- Creating a generic package.
+- Linking the package to the release.
+- Using a tool called [GitVersion](https://gitversion.net/) to automatically determine and increment versions for complex repositories.
+
+You can copy the example project to your own group or instance for testing. More details on what other GitLab CI patterns are demonstrated are available at the project page.
