Categories
Categories organize pages into groups. Add to the bottom of any page to assign it to a category. Each category gets its own index page at /w/<wiki>/c/<name>.
Creating a category

Category pages
Each category has a page listing all member pages, sorted alphabetically. Browse the full list of categories from the sidebar special pages.
