 You can grow a cluster, at anytime, simply by starting up a new node (pick a never before used node ID) and having it explicitly join with the leader as normal, or by passing it a discovery service ID. The new node will automatically pick up changes that have occurred on the cluster since the cluster first started.
 
 # Modifying a node's network addresses
-It is possible to change a node's HTTP(S) address or Raft address between restarts. Simply pass the new address on the command line. You must also, however, explicitly tell the node to join the cluster again, by passing `-join` to the node. In this case what the leader actually does is remove the previous record of the node, before adding a new record of the node.

You must also, however, explicitly tell the node to join the cluster again, by passing `-join` to the node. In this case what the leader actually does is remove the previous record of the node, before adding a new record of the node. You can also change the HTTP API address of a node between restarts, but an explicit re-join is not required if just the HTTP API address changes.
 
 # Removing or replacing a node
 If a node fails completely and is not coming back, or if you shut down a node because you wish to deprovision it, its record should also be removed from the cluster. To remove the record of a node from a cluster, execute the following command at the rqlite CLI:
