+Just serve up the www/ folder using any web server you'd like. To get you set up quickly, we've included a node.js static file server in tools/. Start the server by typing `node tools/server.js` from the command line, and then go to [localhost:8888/www/app.html](http://localhost:8888/www/app.html) in your browser.
