+Generator
+---------
+
+Hackathon Starter Generator is still in alpha stage. It is tighly tied to the
+project code. As soon as you start changing and moving things around, it will
+probably no longer work as expected. That is why it's best to use when you first
+download Hackathon Starter.
+
+:exclamation: **Note:** Generator has a "destructive" behavior, it will physically
+modify your code. *There is no undo action.* To be on a safe side, always commit
+your code to Git, so you could go back and undo the changes.
+
+Currently it supports adding/removing authentication providers and switching
+between SendGrid/Mailgun email services. In the future you'll be able to use
+it to quickly add Socket.io support to your app, add Mozilla Persona sign-in,
+generate new pages (create new routes, templates and controllers for you
+automatically).
