# Categories

> Group Lettercamp articles by category and share filtered homepage views.

Assign a single category to each Lettercamp article using its frontmatter:

```yaml theme={null}
category: "News"
```

Category names are case-sensitive; use consistent spelling across posts. Leading
and trailing spaces are ignored. A post without a category appears under **All**, without a category label.

Select a category above the homepage articles to filter them. The selection is stored in the URL,
for example `/category/news/`, so you can share a filtered view and use your
browser's back and forward buttons. Category pages work in both local preview and
static builds, including without JavaScript.

Each category uses the selected [homepage layout](https://www.lettercamp.com/docs/design/homepage.md) and shows
12 articles per page. Further pages use URLs such as `/category/news/page/2/`.
