Help:Categories
Categories are lists of Articles on Grand Theft Wiki. Not all articles are categorized, and currently we mainly only categorize pages with particular requirements. Pages can be in multiple categories.
When our content base expands, we will have lots of categories such as "Companies", "Mods" and "Cars". If we continue to grow we can subcategorize, such as "Cars in Vice City" and "Characters in Vice City".
You can use Special:Categories to view the list of categories. You can also use Special:Uncategorizedpages to view to list of pages that are not in categories.
