Note: I had trouble with jekyll v0.11.2 on Windows & Ruby193 (maruku would give undefined method errors). I had to gem install jekyll --version '0.11.0', and then uninstall version 0.11.2 of jekyll using gem uninstall jekyll to get it to work. I also had to gem install liquid --version '2.2.2' and uninstall the later version of that, as per this StackOverflow answer.
