+== Importing existing clusters
+
+The pattern supports importing pre-existing {ocp} clusters into the Hub cluster, converting them into *Managed Clusters*.
+
+[WARNING]
+====
+Do not use the `ClusterPools` configuration settings for {rh-rhacm} chart provisioning. The `ClusterPools` technology is limited to cloud environments.
+
+Instead, use the `acm-managed-clusters` chart to import your existing standalone clusters.

+. Copy the `kubeconfig` file of the cluster you want to import to your local system.
+
+. In the `values-secret.yaml` file, define the `kubeconfig` secret by providing the local file system path to the `kubeconfig` file you copied in Step 1.
