get jekyll running
in order to contribute you'll need ruby and 'jekyll' installed: follow this guide: http://jekyllrb.com/ as soon as 'jekyll serve' works, you should be fine
now it's time to clone: git clone https://github.com/tuebix/tuebixorg.git
try jekyll with tuebixorg
just mess around and watch the local changes with "jekyll serve" have fun!
jekyll with github-pages
connection with github was set up along this guide: http://24ways.org/2013/get-started-with-github-pages/
