+###  Running Multiple Citrix Node Controller in the same cluster
+
+When you deploy citrix-k8s-node-controller.yaml, the RBAC and ServiceAccount for `kube-cnc-router` helper pods is created with default value of `kube-cnc-router`.
+If you want to deploy multiple Citrix-Node-Controller in the same cluster, use a different name for these entities in each YAML file and provide this name as environment variable to CNC using `CNC_ROUTER_NAME`.
+
+Following example shows how to specify the `CNC_ROUTER_NAME` environment variable while deploying Citrix node controller via YAML file.
+
+- First, replace the name of ClusterRole/ClusterRoleBinding/ServiceAccount that gets created for `kube-cnc-router` helper pods with a unique name like "someother-rbac-for-kube-cnc-router"
+
+- Set the value of the environment variable in the YAML file as follows:
+
+              - name: CNC_ROUTER_NAME
+                value: "someother-rbac-for-kube-cnc-router"
