The first thing I have people do when learning juju is run ‘juju help commands’, ‘juju help commands | grep thing’ . This immediately exposes the user to the wealth of juju’s capabilities, shows them how to start navigating juju from the cli and helps them understand how they can figure things out for themselves by grepping for what they are trying to do with juju. I still use this tactic to this day. If I want to know what commands are available for manipulating credentials I might run ‘juju help commands | grep credentials’.
