This living style guide is automatically built using kss-node from the pattern library's source stylesheets.

From the documentation, kss-node is:

"a documentation syntax for CSS" that's intended to have syntax readable by humans and machines. Hence, the kss-node software can be used to create a "living style guide".

1. Write human-readable documentation using "KSS syntax" comments. Can be added to CSS, Sass, LESS, or any other CSS Preprocessor files.
2. Have the kss tool automatically build a style guide from your stylesheets.

The repository for this pattern Library and style guide is available on Github.
