The only update to the Quickstart will be some copyediting stuff, as far as we have planned. We'll talk over whatever else we feel like we might need to add but I can't make any promises, commitments, or otherwise on that end.
I'd be remiss if I didn't mention - best way to get direct answers, and help with what's not in the Quickstart, is to join our Discord. Pretty active, especially for A Monster's Tail.
