Excellent, thank you! Her setup looks impressive … I guess I was looking for an MVP of getting going: "You have a Macbook with a built-in webcam? You have a code editor? Great; you're all set. Now do this." This video — https://www.youtube.com/watch?v=Yh5LI_d_JKM — seems like a solid intro to streaming with OBS. Will give it a shot, and will poke around the belly.io streams and see who might be good to connect with.
Also, check out the programming streamers on belly.io! Many of us are happy to answer questions and help out new streamers. :)
