There were also a few dead ends, such as the DarthCoin's bitcoin guide, which doesn't seem to address lightning addresses.
And then of course all the people who wrote something up and at the end they link to DarthCoin's guide saying they got the info from there.
To be clear, these may be fine guides, but they are incomplete. Having a lightning address is a pretty fundamental feature when running your own lightning node. And that's true whether you are on Nostr or not.
