Tutorials
These tutorials are primarily aimed at helping newcomers to the categoryi module in learning the basics of configuration. The category module is a powerful tool, but like a bucket of Lego, it may seem rather daunting and unfathomable, until you learn how to use it. What you do with it is up to you.
Some of the tutorials here may extend beyond configuration, and some may also be above beginner level. But chances are that if it's a nice, hand-holding 'howto' guide for the category module, you'll find it here.
