I can't get a link to a guide right now but searching for Ocean + coinos could give you a hint. The main "issue" (or not) with ocean is that you need a bolt12 ln invoice, if you run a CLN node it's easy, if not, you need some kind of proxy that let you create that bolt12 invoice, coinos is the default setup many people is using and you could connect with nostr with NWC and zap with your mining btc.

So...

- First, you need a wallet you own and can sign with it

- Then you need to create a BOLT12 invoice (coinos)

- Sign with your wallet a messages and configured in Ocean
