Adding Cluster Nodes
~~~~~~~~~~~~~~~~~~~~
You need to enter the root password of the master host when asked for
a password. When joining a cluster using the GUI, you also need to
enter the 'fingerprint' of the master node. You get that information
-by pressing the `Join` button on the master node.
+by pressing the `Add` button on the master node.
CAUTION: Node initialization deletes all existing databases, stops and
then restarts all services accessing the database. So do not add nodes
