What are the best resources to quickly onboard a bitcoiner to nostr?

Thinking about:

* best practive for key creation and storage

* best clients for a purpose and platform

* how to choose relays

* NIP-05 (self hosted)

* become zappable in a self-sovereign way

* best practice to connect a wallet

* run a personal relay for backups

I know some answers and done most of these myself, but curious what is the current best and someone might have even written it all down already. Please share your knowledge 🙏
