 The [livenessprobe side-container](https://github.com/kubernetes-csi/livenessprobe) provided by the CSI community is deployed with the CSI driver to provide the liveness checking of the CSI services.
 
+## Modify Cluster Role
+
+For example, if you want to modify external-resizer RBAC rules, you can do:
+```
+kubectl edit clusterrole external-resizer-runner 
+```
+Replace external-resizer-runner to the role you want to modify

 ## Run example application and validate
 
 Next, validate the deployment.  First, ensure all expected pods are running properly including the external attacher, provisioner, snapshotter and the actual hostpath driver plugin:
 
 ```shell
 $ kubectl get pods

-csi-hostpath-attacher-0      1/1     Running   0          4m21s

 From the root directory, deploy the application pods including a storage class, a PVC, and a pod which mounts a volume using the Hostpath driver found in directory `./examples`:
