The code for the website available at camanjs.com.
The CamanJS website is powered by Jekyll. You'll need Ruby and Rubygems to get started. Don't forget the git submodules as well:
git submodule init && git submodule update
In order to get code highlighting to work, you'll need to have Python and Pygments installed.
sudo easy_install pygments
When you're ready, in the base directory run:
jekyll --auto --server
The site will be available at http://localhost:4000 and changes will automatically recompile.
