This is the boilerplate. It's intended simply as a starting point for building things on top of.
To start building something of your own, download or clone the boilerplate Git repo and start digging around in scene.js to see what's what. By default the boilerplate uses the latest version of the framework hosted on our servers, to make things easy right out of the box.
If you just want the raw source code without the whole git repo, try this in your target folder:
