+## Creating a Release
+
+Creating a new release requires running the [NPM bump version action](https://github.com/grafana/grafana-async-query-data-js/actions/workflows/npm-bump-version.yml). Click `Run workflow` and specify the type of release (patch, minor, or major). The workflow will update package.json, commit and push which will trigger the [Create Release action](https://github.com/grafana/grafana-async-query-data-js/actions/workflows/create-release.yml) which publishes to npm and creates a github release with release notes.
