I created a quick video to help you get started with using Jounce. The video starts with a blank slate, steps through installation of Jounce and the creation of a sample view model for a simple contact record that includes validation.
You can access the video directly at http://vimeo.com/jeremylikness/jounce-getting-started, or view it below:
