and [`helm-push`](https://github.com/chartmuseum/helm-push/#readme),
and is generally not meant for manual consumption.

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)
