Error: Missing app.json

I am trying to migrate a basic react native project into Expo. However, when I open my react native project (created with: react-native init AwesomeProject), it says this

Error: Missing app.json. See https://docs.expo.io/

What do I need to do to migrate a project created with react-native init into Expo?

Thanks!

Updating this very old answer: The best idea right now is probably to just copy your project files into a blank Expo project. Previously we supported a tool called exp convert, but we dropped that awhile ago.

Unless of course you get this message…
‘exp convert’ is temporarily under maintenance and not available

Thanks for bringing that old answer to our attention, this topic is 9 months old and the previous answer was outdated. Closing now.
