 ## Automate Controller Node Joins (Beta) {#automate-node-joins}
 
 With Embedded Cluster, you can use the command line to get the commands for joining controller nodes, rather than having to log into the Admin Console UI to get the commands. This is especially useful when testing multi-node Embedded Cluster installations where you need to automate the process of joining controller nodes to a cluster.
