This is the category for pages which describe something (a host, a piece of software, a person, etc.), as opposed to those which tell you how to do something. For the latter group of pages, use CategoryRecipe.

To add a page to this category, add a link to this page on the last line of that page, as you see on this page with CategoryCategory. You can add multiple categories to a page.
