*The article itself should be a member of the eponymous category. It should be sorted with a space, so that it appears at the start of the category listing (see [[#Sort keys|§&nbsp;Sort keys]] below).
*The article should be listed as the main article of the category using the {{tl|Category main article}} template.
*Articles with an eponymous category may be categorized in the broader categories that would be present if there were no eponymous category (e.g. the article [[France]] appears in both [[:Category:France]] and [[:Category:Countries in Europe]], even though the latter category is the parent of the former category). Editors should decide by consensus which solution makes most sense for a category tree. There are three options:
# Keep both the eponymous category and the main article in the parent category. This is used in [[:Category:Countries in Europe]] to allow that region's country articles to be navigated together.
# Keep just the child article. This is used in [[:Category:British Islands]], to prevent a loop.
# Keep just the eponymous category. This is used for [[:Category:Farmers]] in [[:Category:People by occupation]]. Such "''X'' by ''Y''" categories sometimes cover a limited navigational set, not a topic (see [[#Category tree organization|§&nbsp;Category tree organization]] below), thus there is no logical article content.

If eponymous categories are categorized separately from their articles, it will be helpful to make links between the category page containing the articles and the category page containing the eponymous categories. The template {{Tl|Related category}} can be used for this. An example of this set-up is the linked categories [[:Category:American politicians]] and [[:Category:Wikipedia categories named after American politicians]].
