I'm trying to change the grid system in the Zen theme to use susy but can not find any documentation on how to do it with the 7.5.5 version.
I have installed susy through compass and have added require 'susy' to my config.rb file.
But from here I'm not sure what I need to do.
Do I have to delete the _responsive.scss file that comes with Zen and code my own?
If anyone could provide a run down of the steps needed that would be very helpful.
