+# VolumeGroupReplicationClass
+
+VolumeGroupReplicationClass is a cluster scoped resource that contains driver related configuration parameters for volume group replication.
+
+`provisioner` is name of the storage provisioner.
+
+`parameters` contains key-value pairs that are passed down to the driver. Users can add their own key-value pairs. Keys with `replication.storage.openshift.io/` prefix are reserved by operator and not passed down to the driver.
+
+## Reserved parameter keys

+- `replication.storage.openshift.io/group-replication-secret-name`
+- `replication.storage.openshift.io/group-replication-secret-namespace`
