Editing GoArch:History Project (section)

===== Categories =====
Categories should be placed inside a <nowiki><noinclude></noinclude></nowiki> container. This will prevent them from appearing on pages when the contents of the hahr's page are transcluded into other places.

Every hahr page '''must''' include the following categories:
* <nowiki>[[</nowiki>Category:''<decade>'' BE/DE activity<nowiki>]]</nowiki> (e.g. [[:Category:1100s DE activity]])
* <nowiki>[[Category:{{PAGENAME}}| ]]</nowiki>

The activity category is a hidden organizational category that enables the D'ni decade pages to pull only the contents of that decade from the specific hahr pages that make that decade up. Pages that do not contain the activity category will not be pulled into the decade pages.
