# Content and bilingual routing

Content folders define categories, while frontmatter defines public routes and metadata.



## Folders become categories

The file `content/blog/guides/content-guide.md` belongs to the `guides` category. Category, tag, and archive pages are generated at build time.

## Keep public URLs stable

Give each post a `permalink`. Moving the Markdown source later will not change its public URL.

## Connect translations

Set `translationOf` on the English post to the Chinese route. The theme then produces a language switcher, `hreflang`, and matching sitemap entries.
