This is our top-level category; looking at it another way, it is the root category.

Ideally, every other category should be a subcategory of at least one other, and every article should be in at least one category; many will fit well into two or more (e.g. location, year, and subject-matter).

To add a new category to a page, just add [[Category:Categoryname]] to the end of the article or existing category page.
