As a HEAVILY involved React Native developer, I am strongly suggesting you to NOT use Deco Software. It's pointless. Get Vim or Atom editor if you want to build a React Native app. There are CLI tools anyways to make your life easier. Your hardest battle will be you needing to afford a new computer to be able to run both the iOS simulator and Android simulator (or Genymotion) all at the same time. HMR reloading is already in RN v0.18+ I believe. I'm on 0.20 and it's AWESOME. We even have pull to refresh in now. The RN docs are FINE. Don't use this IDE. Again, don't use it!!! You're better off learning on your own with GitHub. The environment changes so much, because its so new, and things break all the time, that you'll be left in the dust because of this IDE. Just look at my GitHub activity feed to see all the issues that spring up, not to mention all the ones I don't bother documenting because I want to keep moving so fast.
