The static/lib/ directory

This folder should contain all the external Javascript libraries that are needed by your project. It is a good idea to actually include copies of those libraries here instead of linking to a CDN or other URL. This was, far into the future, someone can re-run your experiment without have to hunt down an older version of the libraries you used. By default, the Stroop example includes libraries for Backbone, JQuery, d3.js, and underscore.js. These four are required for psiTurk to work properly but you can add other lirbaries for customization purposes.
