This is a category of templates used for marking articles as requiring cleanup. It is similar to Category:Request templates but the templates here are used in articles themselves instead of on talk pages.
To include a template in this category, add [[Category:Cleanup templates]]
to the <includeonly> section at the bottom of the template's /doc subpage if such a page exists. Otherwise, add <noinclude>[[Category:Cleanup templates]]</noinclude>
to the end of the template code, making sure it starts on the same line as the last character of the code.
Is the article actually worthy of inclusion?
Before placing templates on a page it is worthwhile to cast a critical eye over the page to determine whether it should in fact be included in Wikipedia. Some articles can be tagged for speedy deletion or marked as an article for deletion.
