Getting started

  1. Open the download and drag Fragments to Applications.
  2. Open your React app in Fragments, or start a new one (about two minutes).
  3. Ask for a change. Give it about ten minutes to your first real result: the page before and after, with Undo.
  4. It updates itself. Check now from Fragments › Check for Updates.
