Thanks for it!
I like some of the changes, but not all. That's why i didn't merge it time ago.

I would like to leave in the same place:

• Install using Bower
• Invite me to a coffee
• Creating hugeinc.com website with pagePiling.js

And keep absolute paths instead of relative ones in:

• Who is using it

Why? Because in external referenced documentations like npm (or many others) links wouldn not necessary work.
