Last month the guys over at Top Notch Themes published their free 29 page Ubercart guide. The demonstrate what you need to know so that you can get the most from your Ubercart shopping cart once you've actually added it to your Drupal installation. They go into some pretty good detail about how to best configure the system and which modules to use (hint: most are in the iSite Essentials).

Major topics that are included as part of the guide are:

• How to properly setup the catalog configuration in Ubercart
• Techniques for optimizing site content for SEO

• Simple and straight forward checkout
• Various was to setup product views
