+### GitHub Actions
+
+This repository includes GitHub Actions workflows for:
+
+- Running tests and gem build on every push and pull request (`CI`)
+- Publishing the gem to RubyGems when a GitHub Release is published (`Release`)
+
+To enable publishing, add this repository secret:
+
+- `RUBYGEMS_AUTH_TOKEN`: your RubyGems API key with push permissions
+
+The release workflow uses the `rubygems` environment and pushes the built gem automatically.
