Open source is built on a simple idea: what you learn, you share. 🎃

What's one thing you've learned from contributing that could help the next first-timer?

We said… nah. 💀

Somehow got 150+ builders into the venue, shipped crazy shit, and ran 3 sessions on Hacktoberfest, Open Source &amp; Devcon.
