Starting with ZURB Foundation 5, they use Bower to distribute the assets, and in their “getting started” guide they propose to install bower.
I have not yet installed bower myself, but there is a really easy alternative: use rails-assets.org.
At the top of your
Gemfile add a source line:
source 'https://rubygems.org' source 'https://rails-assets.org' ## <---- add this line
and then add the gem
//= require foundation
And in your
*= require foundation
