+:::info Automated CI Deployment
+
+When a release tag is created (e.g., `v1.5.0`), the GitHub Actions CI will
+automatically:
+
+- Create a versioned copy of the documentation
+- Build the documentation with the new version included
+- Deploy the updated documentation to GitHub Pages
+- Upload versioned documentation archives as release assets
+
+This means the documentation versioning and deployment is handled automatically
+as part of the tag creation process.
