"snapcraft.yaml - Snapcraft 8.11.2 documentation":

"the service will be started with craftctl and another management agent, which is most commonly a hook"

The linked documentation doesn't explain this. How can craftctl be used to start a service? I was not able to get the command's usage (tried --help/-h/help).

Perhaps this meant to say: "the service can be started with snapctl, most commonly from hook" ?
