 For your convenience, Fleet provides a script that can automate the process of joining a cluster
 onto a hub cluster. To use the script, run the commands below after creating needed AKS clusters:
 ```sh
-# Pass in the hub cluster name and a list of cluster context names (separated by a space) as arguments to the script that you would like to 
-# join the fleet as member clusters. Their context will be used to access the cluster.
