To me this seems more like something each app on Nostr should build for their users. “Get started on Damus” “…on Habla” “…on Zap.stream” and so on. It’s kind of like trying to build a “getting started on the internet” guide. There are maybe a handful of concepts that apply to all sites (Nostr address, npub/nsec, zaps, etc) but beyond that, so much depends on the specific application running on the protocol and their individual UI and design choices. 

 Exactly! 
That's a great way of saying it also: Get started on the internet 👌
