Display category description on catalogue page

[diddydotdash]

Sorry if this is answered elsewhere ... I have looked, with no success!

So I have added 2 categories and have sorted my products into those two categories. When the customer shops and chooses one of the two categories a table of products is displayed with the category title above them at the top of the page. I would like to display the category description underneath the category title. Is there a way of doing this?

Thanks in advance.
