# Rolldown

Source: https://plumeria.dev/docs/integration/rolldown





[`examples/rolldown`](https://github.com/zss-in-js/plumeria/tree/main/examples/example-rolldown) shows how to use [`@plumeria/unplugin`](https://www.npmjs.com/package/@plumeria/unplugin) in rolldown.\
The unplugin compiles Plumeria styles into the CSS asset produced by rolldown.

`npx @plumeria/init` detects Rolldown and writes this setup for you; see [@plumeria/init](/docs/api-reference/init). The rest of this page is the same setup by hand.
