Are you using Damus? Easiest way generally is to download the ‘Wallet of Satoshi’ app, once you open it you can go to lightning address and copy the address that starts with LNURL and put that into your profile here to get started.

Also, post a note or two asking for help and use the hashtag #plebchain and you can hopefully find some good people to help walk you through it if you’re still having issues. 🤙🏻
