-This uses [@helm/chart-releaser-action](https://www.github.com/helm/chart-releaser-action) to turn your GitHub project into a self-hosted Helm chart repo. It does this – during every push to `master` – by checking each chart in your project, and whenever there's a new chart version, creates a corresponding [GitHub release](https://help.github.com/en/github/administering-a-repository/about-releases) 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
