Categories group related pages and build the left-hand navigation.
| To do this | Do this |
|---|---|
| Add a page to a category | Put [[Category:...]] anywhere in the page and save. It shows as a tag at the bottom of the page. |
| Add a page to several categories | Add one [[Category:...]] line for each. |
| Remove a page from a category | Delete that line and save. |
| Describe a category | Open the category, click Create this page if it has no page yet and write a description. |
| Make a subcategory | Add [[Category:Blocks]] to the Category:Ores page. Ores now sits inside Blocks. |
| Link to a category without joining it | Put a colon first: [[:Category:Weapons]]. |
A category is different from a Parent page. Categories group pages in the menu, while a parent page only adds the breadcrumb trail above one page.
