Javascript Include Tags in

To enable markdown in Reveal.js this script is needed:

Reveal.initialize({
controls: true,
            progress: true,
            history: true,
            center: true,

            transition: 'slide', 

dependencies: [
    // Cross-browser shim that fully implements classList - http://ift.tt/1vZeZ06
    { src: 'lib/js/classList.js', condition: function() { return !document.body.classList; } },

    // Interpret Markdown in <section> elements
    { src: 'plugin/markdown/marked.js', condition: function() { return !!document.querySelector( '[data-markdown]' ); } },
    { src: 'plugin/markdown/markdown.js', condition: function() { return !!document.querySelector( '[data-markdown]' ); } },
]
            });

As I'm implementing this in a rails view, how can I get those src's working?
