        Homebrew for Mac OS X
        <ul>
          <li>Since Elixir requires Erlang R16B, first call <code>brew tap homebrew/versions</code> and then <code>brew install erlang-r16</code></li>
          <li>If you have a previous Erlang version installed, unlink it with <code>brew uninstall erlang</code> and link the new one with <code>brew link erlang-r16</code></li>
          <li>Update your homebrew to latest: <code>brew update</code></li>
          <li>Install Elixir: <code>brew install elixir</code></li>
        </ul>
        </li>
        <li>Fedora 17+ and Fedora Rawhide: <code>sudo yum -y install elixir</code></li>
        <li>Arch Linux : Elixir is available on AUR via <code>yaourt -S elixir</code></li>
        <li>Other:  Get <a href="http://www.erlang.org/download.html">Erlang R16B</a>, then download a <a href="http://elixir-lang.org/packages.html">precompiled package</a></li>
