  shortDescription: Deploy and manage MinIO Operator and Tenant(s)
  description: |
    The kubectl-minio plugin wraps the MinIO Operator and provides a simplified 
    interface to create and manage MinIO tenant clusters.
  caveats: |
    * For resources that are not in default namespace, currently you must
      specify -n/--namespace explicitly (the current namespace setting is not
      yet used).
