-When opening a support case, you can give information about your cluster to Red Hat Support by providing the unique identifier (UID) of your cluster. To uniquely identify a {microshift-short} cluster, use the `kube-system` namespace metadata UID.
+When providing information to Red{nbsp}Hat Support, it is helpful to provide the unique identifier of your cluster. For {microshift-short}, you can get your cluster ID manually by using the {oc-first} or by retrieving the ID from a file.
