Sass kickstart is a simple and fast setup environment for frontend developers who want to use or start to use SaSS, CoffeScript, Haml. Also it contains Compass and Twitter Bootstrap framework.
Project based on ruby framework Sinatra. So you need an environment for executing ruby application. I recommend to use RVM
If you are not experienced with setup such environments, you can try to use installer for ubuntu.
If you already have an environment just do following:
$ git clone firstname.lastname@example.org:ExReanimator/sass_kickstart.git $ cd sass_kickstart $ bundle install $ unicorn
unicorn will run unicorn server and application will allowed at http://0.0.0.0:8080
