During my time learning how to set up a #Lightning node, I found it useful to think of the node and wallet in #Nostr terms:

#Lightning node -> #Nostr relay

nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5 wallet app -> #Nostr client

It might not be a 100% accurate comparison, but it did help me process how setting up a channel all comes together
