 In future operations, you can also use the following options:
 
 - `--dry-run` - dry run mode will show a diff with the existing configuration.
 - `-m try` - try mode will rollback the configuration in 1 minute.
 
+Now, bootstrap the cluster by running this command against the first node (only for first node!):
