Category:Help contains help pages that describe how to use this wiki. 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]]), for documentation of this wiki core interface, or Category:Extension help (using [[Category:Extension help]]) for extension documentation. 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.

The front page is Help:Contents
