+# OKE Enhanced Clusters and Virtual Nodes
+
+CAPOCI supports OKE [Enhanced Clusters][enhanced-cluster] and [Virtual Nodes][virtual-node-pool]. A cluster-template 
+`cluster-template-managed-virtual-node.yaml` with Enhanced Cluster and Virtual Node Pool has been released in 
+CAPOCI release artifacts which can be referred using  the flavor `managed-virtual-node` in `clusterctl generate` 
+command.
+
+
+## Create Enhanced Cluster
+The following `OCIManagedControlPlane` snippet can be used to create an enhanced OKE cluster.
+
+```yaml
+kind: OCIManagedControlPlane
+apiVersion: infrastructure.cluster.x-k8s.io/v1beta2
+spec:
+  clusterType: "ENHANCED_CLUSTER"
+```
+
+## Create Virtual Node Pool
+
+The following `OCIVirtualMachinePool` snippet can be used to create a Virtual Node Pool. Please read through [CAPOCI 
+API Docs][api-docs] to see all the supported parameters of `OCIVirtualMachinePool`.
+
