smi_23 is right, but that templating tutorial will only take you so far. If you just want to see the approximate end product of following it, visit my Visioncart test site at
http://stagingdomain.info (subject to go away without notice!).
At the moment, the docs for Visioncart are radically incomplete, and the software itself is full of holes. Both of these problems are being worked on, to some extent, by the development team. The best source for information right now is the
Visioncart forum. Spend awhile thumbing through there and you'll have a general idea of what you're getting into. A number of salient issues are addressed.
If you're persistent and willing to get your hands dirty up to the elbows, you can make Visioncart work. We just launched a couple of sites with it, to which I can send you links if you PM me.
