title: Converting Existing React Native Projects to Expo
body: <p>I'm considering building mobile apps in React Native using Expo and I noticed under FAQ that existing React Native projects can be converted to Expo.</p>
  
  <p>What exactly are we converting? I really like staying as pure and clean as possible without too many abstraction layers in the middle which can obscure my ability to understand what's really happening for things to work in the app.</p>
  
  <p>I'd appreciate a bit more clarification about what's really happening in the conversion process and what Expo is adding to the existing project.</p>
