Please visit http://code.google.com/p/youtube-direct-lite/ for the most up to date information on deploying and using YouTube Direct Lite. If you are using a local deployment, it is recommended that you concatenate and minify all the JavaScript source files for performance reasons. You can do this by running node r.js -o app.build.js from within this top-level directory; it will output a static-min/ directory containing the optimized JavaScript, which you can then serve. More information about this process, including the dependencies you need to install to run those commands, can be found at http://requirejs.org/docs/optimization.html
