Wiki Pro doesn't show categories or tags I've added

An earlier answer to not being able to see the wiki on my site was to type /wiki/ after the address. That takes me there, but doesn’t show any categories or tags. I want the categories to be on the left just like wikipedia. And I want everything linked.

In the center, I want to have 3 articles/summaries with the [more…] capability.

And additional sorting tools on the right. Am I asking for too much?

I’ve tried searching wiki pro, but can’t find a getting started manual.
