This release integrates Bower as a means of controlling assets similar to the main Zurb project. Please take the time to install bower and Grunt if you have not done so already, because you will need it as a themer.
To get the latest assets (SCSS, JS) from Zurb, navigate to your theme in terminal and do the following:
This will copy anything updated into a bower_components folder. From here, running grunt will copy those into their rightful places in the theme.
This release has removed Ruby/Compass support and in its place added Grunt.js support inline with Foundation 5. The README.txt in the STARTER folder has installation instructions. Grunt.js now takes care of compiling and watching changes to SCSS and CSS files for you.
