To generate the docs, you'll need jekyll.
sudo gem install jekyll -v 0.12.0
sudo gem install liquid -v 2.4.1
sudo gem install redcarpet -v 2.1.1
sudo gem install maruku -v 0.6.0
sudo gem install rdiscount -v 1.6.8
sudo gem install RedCloth -v 4.2.9
Then you can run: jekyll serve --watch
And browse the site at http://localhost:4000/
