You can find some samples here.
Getting Started
If you know Polymer, the easiest way to get started is by adding guara-elements#master as a bower dependency and incluing guara-elements.html in your index.html.
<link rel="import" href="bower/guara-elements/guara-elements.html">
Please note that guara-elements.html will import all guara elements and polymer
If you don't know Polymer, I'm sorry :)
