+Deploy RSCT/RMC on an OCP Cluster on PowerVM
+=========
+
+These instructions will help you deploy the RSCT/RMC daemonset on an OCP cluster running on PowerVM:
+
+**1. Setting up the inventory**
+
+Use the instructions provided [here](https://github.com/ocp-power-automation/ocp4-playbooks#setting-up-inventory) to setup the inventory for your cluster. For deploying RSCT, you would only need to set the bastion host details in the inventory.
+
+
+**2. Set up the variables**
+
+Make use of the sample file at examples/rmc_vars.yaml.
+
+```
+cp examples/rmc_vars.yaml .
+```
+
+**3. Run the playbook to deploy RSCT**
+
+The ocp-customization [module](https://github.com/ocp-power-automation/ocp4-playbooks/tree/master/playbooks/roles/ocp-customization) is used to deploy RSCT/RMC daemonset on the cluster.
+
+```
+ansible-playbook -i inventory -e @rmc_vars.yaml playbooks/customization.yaml
+```
+
+**4. Post deployment checks**
+
+After the playbook execution completes, the daemonset and pods should be available in the `powervm-rmc` namespace on the cluster. Run the following command to list them:
+
+```
+oc get daemonset,pods -n powervm-rmc
+```
