Suppose we would like to make an information block on the page that lists our courses in the Miscellaneous category? We want to put general information there about the courses, but we don't want it cluttering up the courses themselves; nor do we need it in any other category pages? Note that you'd need appropriate permissions to edit this page; a regular teacher wouldn't be able to add to a course category page.

To achieve this, we start at our Miscellaneous course category page, which for us is: http://www........../ course/category.php?id=1

A user, logged in or not, coming to this page now will see this extra information block. The following screenshot shows our student Emma's view. Once she goes into a course, however, because of the way we set it up, the block is no longer there.
