Hi Adam, I’m a newbie to this as well! not saying this is the best or whatever, but here is a link I used, and it couldn’t have been simpler to set up my lightning wallet so that I could zap. you can get this information from your profile and it’s only a couple of questions then it will allow you to purchase Satoshi’s through the Primal app so you can zap people. hooe this helps! https://bitcoinnostr.com
