  1. unzip the folder on your own machine
  2. navigate to the ‘debug’ folder and open ‘sample.html’

  1. Ideally, you should probably consider configuring a local web server like Apache or IIS to develop with (so that you can load your applications using ‘http://’ protocol in a browser instead of relying on ‘file:///’), but it's just cool to say that digging into the source is as easy as 1, 2, 3
