Your laptop and your phone. Make sure you have Expo Go installed on your phone. Yes, it works with both iOS and Android. No, it doesn't matter whether you have a PC or Mac - anyone can join.

The workshop is action-packed and the better prepared you are, the more we can cover. Also WiFi can act up at the worst moments - especially when everhone is pinging the same servers at once. Please try to install Expo Go to your phone before class. It will help if both your devices and yourself are operating on full batteries.

Yes, the workshop is geared for beginners. The main activities will take place in the browser and on the web. Some familiarity with the command line and code editor such as VS Code or Atom is helpful. But not absolutely necessary.

Yes, I'm looking forward to the day and can stick around for a bit after the workshop. I'll be happy to answer any questions you have.
