link to how to install zurb foundation

I'm trying to follow the 2.9 guide while riding alchemy-cms 3.0.

At this point the 2.9 guide wasn't working anymore for me as to install zurb foundation I had to follow [their guide](http://foundation.zurb.com/docs/applications.html) so I drafted the 3.0 guides accordingly.

If you like this approach I could try and go on updating the 3.0 guide.
