-## RBAC
-By default the chart will not install the recommended RBAC roles and rolebindings.
 
-You need to have the flag `--authorization-mode=RBAC` on the api server. See the following document for how to enable [RBAC](https://kubernetes.io/docs/admin/authorization/rbac/).
-
-To determine if your cluster supports RBAC, run the following command:
-
-```console
-$ kubectl api-versions | grep rbac
-```
-
-If the output contains "beta", you may install the chart with RBAC enabled (see below).
-
-### Enable RBAC role/rolebinding creation
-
-To enable the creation of RBAC resources (On clusters with RBAC). Do the following:
-
-```console
-$ helm install --name stash-operator appscode/stash --set rbac.create=true
-```
