-If you are permanently removing the host from the MarkLogic cluster, once the pod is terminated, follow standard MarkLogic administrative procedures using the administrative UI or APIs to remove the MarkLogic host from the cluster. Also, because Kubernetes keeps the Persistent Volume Claims and Persistent Volumes around until they are explicitly deleted, you must manually delete them using the Kubernetes APIs before attempting to scale the hosts in the StatefulSet back up again.
+If you are permanently removing the host from the MarkLogic cluster, once the pod is terminated, follow the section "Recovery - Step 3: Remove dead host configuration" in [MarkLogic KB article](https://help.marklogic.com/Knowledgebase/Article/View/607/15/replacing-a-failed-marklogic-node-in-a-cluster-a-step-by-step-walkthrough).

+In order to delete the Persistent Volumes and Persistent Volume Claims of the terminated host first run the below command to get the Persistent Volume Claims:

 ### Enabling SSL over XDQP
 
 To enable SSL over XDQP, set the `enableXdqpSsl` to true either in the values.yaml file or using the `--set` flag. All communications to and from hosts in the cluster will be secured. When this setting is on, default SSL certificates will be used for XDQP encryption.
