The website runs on GitHub Pages and uses Jekyll for generating static HTML from templates.
Each event (iteration) is represented as a 'post' (e.g. _posts/2011-12-03-global-day-praha.html).
To preview the site on local machine use prepared vagrant machine. The vagrantfile is already part of repository.
$ vagrant up
$ vagrant ssh
vagrant@precise32:~$ cd /vagrant/
vagrant@precise32:/vagrant$ jekyll serve -w
Alternatively, if you prefer Docker, you can use docker image for github pages
docker run -t --rm -v "$PWD":/usr/src/app -p "4000:4000" starefossen/github-pages
