 OpenShift Master Certificates
 ========================
 
-TODO
+This role determines if OpenShift master certificates must be created, delegates certificate creation to the `openshift_ca_host` and then deploys those certificates to master hosts which this role is being applied to. If this role is applied to the `openshift_ca_host`, certificate deployment will be skipped.
