I think I'm getting Lightning figured out. Slowly. I have Zeus installed and created an invoice but haven't opened a channel yet because I don't know how to get any of my on chain Bitcoin onto Lightning. Oh and I don't know how to connect my Lightning address into my Nostr profile yet. Baby steps.  

 My first Lightning invoice. https://image.nostr.build/4f5938cae014b67d2e3f61a4dd116d89fc5441198d880b764125d4b8e5533581.jpg 

 You will need to open a channel before you can send or receive bitcoin over lightning and nostr.
