Help:Categorization

Categories help organize the wiki and make it easier for readers to find content. Categories an article is a member of are listed at the top and the bottom of the article. Readers can also browse the content available on the wiki starting at Category:Roblox, the highest-level category for all articles in the 's category system.

Categories intended for articles (and subcategories of articles) are divided between topic categories and set categories. A topic category contains articles that are about a topic and is generally named after that topic, in singular. Category:Avatar shop is an example of a topic category. A set category contains articles about instances of a class of things and is named after that class, in plural. Set categories can also contain lists of instances of the class. Category:Avatar shop items is an example of a set category (in this case, one that does not contain articles directly but rather through subcategories).

Some categories, called hidden categories, are hidden at the bottom of pages unless the option to show hidden categories is enabled in Special:Preferences. Category:Hidden categories has a list of these categories. Other categories, listed in Category:Special categories are populated automatically by the MediaWiki software or by extensions.

Some categories are intended to be populated only by templates. Before adding a category to a page, check the category page (in the Category namespace) for any notes about what pages belong in the category.
