+
+### Releases
+There's a [release workflow](.github/workflows/release.yml) to automate releasing the Helm charts.
+It uses [Helm Chart Releaser Action](https://github.com/marketplace/actions/helm-chart-releaser)
+which turns this project into a self-hosted Helm chart repository.
+It does this – during every push to `main` – by checking each chart in the project,
+and whenever there's a new chart version, creates a corresponding GitHub release
+named for the chart version, adds Helm chart artifacts to the release,
+and creates or updates an `index.yaml` file with metadata about those releases,
+which is then hosted on GitHub Pages at https://helm.packit.dev.
