The actual categories and other uploaded files such as images may be cate-gorized in the same way as normal pages. It is useful to connect the article-categories with the categories that are already in place so as to establish connections and hierarchies. Once you save the article, follow the category links at the end of the page to see if the category is already created and if not, categorize them until you connect them with an existing category.

For example, Category:american Artist should be in both the Category:artists by nationality and the Category:american people.
