There really doesn't seem to be much to say about the "onboarding" ... unless I'm missing something, it just dumped me into an empty interface and invites me to create my own space or enter an invite code. Lacking an invite code there doesn't seem to be any way to join a demo space in order to get a feel for how it even works. Quite anticlimactic, IMO.
