Darkzen – how do I upload ads

For a new blog I selected Darkzen precisely because it seemed to mimic the templates that some of the blogging gurus us: double column with lots of ad space blocks.

The problem: I can’t seem to find instructions on how to populate these dedicated ad spaces. I have been successful in posting banners on the blog, but not in these spaces.

Can someone please point me in the right direction for the instructions on how to do this?

thank you.
