Log in to zap.stream, hit the (+) top right, click "dashboard", click "start stream", type in your details, then copy paste your stream key into either OBS on your laptop or whatever phone client you want to stream with ( i use prism), fund your zap.stream account with sats under dashboard and balance by generating an invoice, and then you can go live.

If you want me to show you we can hop on corny chat or I can screen share the process. Just lmk.

Its easier to show it than it is to explain it sometimes.
