Category:Help contains help pages that describe how to use MediaWiki. Only pages in "Help:" namespace should be in this category.
All English-language public-domain help pages should be categorized into Category:Help (using [[Category:Help]]). Additional categories for further sorting is also helpful. This is needed because of later half-automated creation of the PD Help package from this category.
