Instructions not clear, demo snippet should help

[floranknz]

I'm trying to use it, but the documentation isn't very clear as :

1. We don't know exactly which class we should call
2. Section about custom prefix isn't clear as the snippet displayed can't be used alone

I tried to use classes like described at the bottom (the same as animate.css documentation) but it is not working.

I think this project would benefit greatly from a demo.
