+=========
+
+This role prepares agents on an on-premise inventory (whether bare metal or virtualized) for provisioning. The nodes must be accessible via Virtual Media.
+
+Requirements
+------------
+
+* The nodes must be reachable via Virtual Media.
+* Access to an OpenShift cluster with ACM and MCE operators
+* Access to a valid kubeconfig file available using the `KUBECONFIG` environment variable.
+* AgentServiceConfig and Provisioning configured on the host cluster
+
+Role Variables
+--------------
+
+The following variables can be set to customize the role behavior:
