Google has teamed with Code School to produce a training course that covers the developer tools available in Chrome for developing and debugging web apps.
Chrome's Developer Tools are based on the WebKit inspector and give developers deep access into the internals of the browser and their web applications.
As is often the case with open source tools, there's a lot to learn in order to use them to their full potential, hence the need for some training materials. As Paul Irish explains on the Chromium blog:
In each you start with an overview video and then complete a series of challenges, for which you receive immediate feedback and also earn points. There are badges for each successfully completed chapter. In all there are over 75 challenges

The course is free to anyone who has enrolled in Code School and will require fifteen or more hours to complete.
