### Bug Description I wanted to initialize a machine charm. I looked up the `charmcraft init` help: https://juju.is/docs/sdk/charmcraft-init . (Issue 1) It mentioned the `--profile` option but not what arguments it could take (other than to say it defaults to `simple`, which was also not defined). I gave up and just ran the command without selecting a profile. Then I noticed (Issue 2) the charm it had initialized by default was a Kubernetes charm. Also, (issue 3) the comment at the top of the `charm.py` file linked to quick-start guide (https://discourse.charmhub.io/t/4208) that is not published in the docs and which doesn't really make much sense (e.g., it contains instructions on how to install `charmcraft` and how to run `charmcraft init` but, if you've come to this page from the charm.py produced by `charmcraft init`, then you already know how to do all that). I think we should document all the possible arguments for `--profile`, not apply any default to `charmcraft init` (prompt the user to choose), and link only to official docs. ### To Reproduce Issue 1: Run `charmcraft init --help` or visit https://juju.is/docs/sdk/charmcraft-init . Issue 2: Run `charmcraft init`. Issue 3: Inspect the contents of the `charm.py` file generated by `charmcraft init`. ### Environment Not applicable. ### charmcraft.yaml ```shell Not relevant. ``` ### Relevant log output ```shell Not relevant. ```
