Hello @DanGould

In the tutorial, we have several options the user can setup the wallet and I think it will be a challenge for new comers. maybe we can make it somehow easier so we can demonstrate mainly payjoin functionality and not let the user get distracted setting up wallets.

best options I though about:

1. use regtest in the test and link to regtest setup in bitcoin-core. choosing regtest over testnet here because it would take time for blockchain to download..
2. use testnet and setup the wallet in the tutorial(ie share xpriv or mnemonic) then the user basically doesnt need to create any wallet.(this is the easiest from user perspective)

one argument for using testnet over regtest is that we could point the user to see the tx in mempool.space

very initial document is here ed2c2f0

we could also take the mutiny route where we load a bdk wallet with in-memory database and point them to a faucet

Do you have a link please?

if you run this it'll connect to their signet electrum server https://github.com/mutinywallet/mutiny-node and anyone can use their faucet https://faucet.mutinynet.com/

This pr should not depend on PjUriBuilder. That should keep us from being blocked on that issue and allow us to triage this independently

Is it possible to split the docs removal? It's easier to review PRs in isolation, and I'm not sure if this is doing two things (as the title implies) or many, as the commit log seems to imply. Ideally it's doing one main thing
