I've rebuilt Base SCSS to work as a simple, minimalist companion to existing tools like Bourbon and Neat. It's not made to replace the aforementioned tools. It just offers an additional set of things I've written for use on real world projects.
Now you can install it via Bower! Navigate to your project in your favorite command line tool and run:
bower install base-scss
