stderr stream
Use wording that suggests what is it that people might normally find, if the command didn’t return an empty state.E.g
$ multipass list
No instances found.
Empty states, where nothing is created or connected yet, are not errors.
If there is an obvious command, or set of commands that can be suggested to the user to create/add/connect a thing, so the action doesn’t return an empty state - provide it within the output.
E.g
$ juju list-controllers
No controllers registered.
You can either create a new controller using "juju bootstrap" or connect to
