+# Create IBM VPC Cluster Using ClusterClass
+
+## Preface
+- To deploy IBM Cloud VPC workload cluster using [ClusterClass](https://cluster-api.sigs.k8s.io/tasks/experimental-features/cluster-class/index.html), create a cluster configuration from the [clusterclass-template](https://github.com/kubernetes-sigs/cluster-api-provider-ibmcloud/blob/main/templates/cluster-template-vpc-clusterclass.yaml).
+- The [clusterclass-template](https://github.com/kubernetes-sigs/cluster-api-provider-ibmcloud/blob/main/templates/cluster-template-vpc-clusterclass.yaml) will use [clusterresourceset](https://cluster-api.sigs.k8s.io/tasks/experimental-features/cluster-resource-set.html) and will create the necessary config map, secret and roles to run the cloud controller manager
+- The flags EXP_CLUSTER_RESOURCE_SET and CLUSTER_TOPOLOGY need to be set to true.
+
+A comprehensive list of IBM Cloud VPC Regions and Zones can be found [here](/reference/regions-zones-mapping.html)
