+# Helm API
+
+This is the API documentation for [Helm](../../user/packages/helm_repository/index.md).
+
+WARNING:
+This API is used by the Helm-related package clients such as [Helm](https://helm.sh/)
+and [`helm-push`](https://github.com/chartmuseum/helm-push/#readme),
+and is generally not meant for manual consumption. This API is under development and is not ready
+for production use due to limited functionality.
+
+For instructions on how to upload and install Helm packages from the GitLab
+Package Registry, see the [Helm registry documentation](../../user/packages/helm_repository/index.md).
+
+NOTE:
+These endpoints do not adhere to the standard API authentication methods.
+See the [Helm registry documentation](../../user/packages/helm_repository/index.md)
+for details on which headers and token types are supported.
