Hey! Thank you!!! Is it supposed to be like an email address?
Welcome, I tried to Zap you some sats through this post but you don't have it set up.
Its really easy to set up just download Wallet of Satoshi from the app store
https://apps.apple.com/us/app/wallet-of-satoshi/id1438599608
https://play.google.com/store/apps/details?id=com.livingroomofsatoshi.wallet
Open the app click Receive
Then click the lightning address
It should now be copied. Go to your Nostr profile and paste it where it asks for a lightning address. Now people can send you some bitcoin ⚡️

Yea its like an email address but for your bitcoin! Wallet of Satoshi is a custodial wallet I recommend it off the start because of how easy it is. I use it with small amount of funds for tipping and receiving tips. Never store large amount of funds on there. I always recommend sweeping it out to a wallet you control if you ever hit a big amount on there. Welcome to Nostr!
