*   Install Xcode
*   Run Xcode, go to **Preferences**
    *   Sign-in under "Accounts"
    *   Tab over to "Downloads" and click the teeny arrow for "Command
        Line Tools"
*   Once installed, install Homebrew

        ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go)"

*   Then install the Ruby Version Manager[^1]

        curl -L https://get.rvm.io | bash -s stable --ruby

*   Source the RVM:

        source /usr/local/rvm/scripts/rvm

*   Install Jekyll

        gem install jekyll

*   Test. I did it by running `jekyll serve` from a
    [Bootstrap](http://getbootstrap.com/) download[^2].
