+## RSCT Deployment on OpenShift Clusters
+
+### Prerequisites for OpenShift Clusters
+- OpenShift cluster with at least one Power node and admin access.
+- Create a CatalogSource using the image `ghcr.io/ocp-power-automation/rsct-operator-catalog:latest` in the `openshift-marketplace` namespace.
+```
+oc create -f - <<EOF
+apiVersion: operators.coreos.com/v1alpha1
+kind: CatalogSource
+metadata:
+  name: rsct-catalogsource
+  namespace: openshift-marketplace
+spec:
+  displayName: RSCT Operator
+  publisher: IBM
+  sourceType: grpc
+  image: ghcr.io/ocp-power-automation/rsct-operator-catalog:latest
+EOF
+```
+- Use `rsct-operator-system` namespace for RSCT deployment.
+    
+### Operator Deployment
+1. Create the `rsct-operator-system` namespace
+```
+oc create -f - <<EOF
+apiVersion: v1
+kind: Namespace
+metadata:
+  name: rsct-operator-system
+EOF
+```
+
+2. Create an OperatorGroup for the RSCT Operator
+```
+oc create -f - <<EOF
+apiVersion: operators.coreos.com/v1
+kind: OperatorGroup
+metadata:
+  name: rsct-operator-operatorgroup
+  namespace: rsct-operator-system
+spec:
+  targetNamespaces:
+  - rsct-operator-system
+EOF
+```
+
+3. Create an Subscription for the RSCT Operator
+```
+oc create -f - <<EOF
+apiVersion: operators.coreos.com/v1alpha1
+kind: Subscription
+metadata:
+  name: rsct-operator-subscription
+  namespace: rsct-operator-system
+spec:
+  channel: "alpha"
+  installPlanApproval: Automatic
+  name: rsct-operator
+  source: rsct-catalogsource
+  sourceNamespace: openshift-marketplace
+EOF
+```
+
+4. Verify the operator deployment
+```
+# oc get csv -n rsct-operator-system
+NAME                           DISPLAY                                      VERSION        REPLACES                      PHASE
+rsct-operator.v0.0.1-alpha2    RSCT Operator for IBM Power Systems          0.0.1-alpha2                                 Succeeded
+
+# oc get pods -n rsct-operator-system
+NAME                                                READY   STATUS    RESTARTS   AGE
+rsct-operator-controller-manager-7978b6f4cd-kjsmd   2/2     Running   0          28s
+```
+
+###  Create the Custom Resource
+After deploying the operator, you must create an RSCT object. The following example will create an RSCT instance.
+```
+oc create -f - <<EOF
+apiVersion: rsct.ibm.com/v1alpha1
+kind: RSCT
+metadata:
+  name: rsct
+  namespace: rsct-operator-system
+spec: {}
+EOF
+```
+
+The RSCT image can be configured in the spec.
+```
+spec:
+  image: quay.io/powercloud/rsct-ppc64le:latest
+```
+Default image is `quay.io/powercloud/rsct-ppc64le:latest`
+
+**Verify the RSCT deployment:**
+```
+# oc get pods -n rsct-operator-system
+NAME                                                READY   STATUS    RESTARTS   AGE
+rsct-brs49                                          1/1     Running   0          13s
+rsct-c2q54                                          1/1     Running   0          13s

+rsct-operator-controller-manager-7978b6f4cd-kjsmd   2/2     Running   0          66s
+rsct-r6tdl                                          1/1     Running   0          13s
