 - `charts_dir`: The charts directory
 - `charts_repo_url`: The GitHub Pages URL to the charts repo (default: `https://<owner>.github.io/<project>`)
 - `skip_packaging`: This option, when populated, will skip the packaging step. This allows you to do more advanced packaging of your charts (for example, with the `helm package` command) before this action runs. This action will only handle the indexing and publishing steps.
+- `skip_update_index`: This option, when populated, will skip updating helm chart repo index.
