 ## Deploying a Multiple MarkLogic Cluster with Multiple Groups
 
-To deploy a MarkLogic cluster with multiple groups (separate E and D nodes for example) the bootstrapHostName and group.name must be configured in values.yaml or set the values provided for these configurations using the --set flag while installing helm charts.
-For example, if you want to create a MarkLogic cluster with three nodes in a "dnode" group and two nodes in an "enode" group, run the following helm commands:

+For example, if you want to create a MarkLogic cluster with three nodes in a "dnode" group and two nodes in an "enode" group, start with the following helm command:
 
 ```
 helm install dnode-group ./charts/ --set group.name=dnode --set replicaCount=3
 ```
-Once this deployment is complete, a MarkLogic cluster with three hosts in it should be running.
-To add the "enode" group and nodes to the cluster, the bootstrapHostName must be set to join the existing MarkLogic cluster. First host in the other group can be used. For this example, set bootstrapHostName to dnode-group-marklogic-0.dnode-group-marklogic-headless.default.svc.cluster.local with the following command:
