+ This step is only required when helm install should be done on different releasename/prefix from rest of ONAP deployment
+
+With Istanbul release, OOM team included support for ServiceAccount in ONAP deployment to limit the pod access to API server.

+Following packages has been added under oom/common to support pre-provisioning of cluster roles and ServiceAccount management
+
+ * `ServiceAccount <https://git.onap.org/oom/tree/kubernetes/common/serviceAccount/values.yaml>`_
+ * `RoleWrapper <https://git.onap.org/oom/tree/kubernetes/common/roles-wrapper>`_
+
+When deployed, these chart will create the ServiceAccount and Role (based on override) and required Rolebinding (to associate the Serviceaccount to a role).
+
+ONAP deployment by default includes the required provisioning of roles under release name (such as "dev") under which ONAP is deployed. For subsequent
+helm installation under same release name prefix (i.e dev-) no further action is required.

+When Helm install is required under different releasename prefix, then execute following command prior to running helm install.
