+# Example app with cssed
+
+This example shows how to use [cssed](https://github.com/okotoki/cssed), a CSS-in-JS library, with Next.js.
+
+We are creating `div` element with local scoped styles. The styles includes the use of pseudo-selector.
+
+## Deploy your own
+
+Deploy the example using [Vercel](https://vercel.com):
+
+[](https://vercel.com/import/project?template=https://github.com/vercel/next.js/tree/canary/examples/with-cssed)
+
+## How to use
+
+Execute [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app) with [npm](https://docs.npmjs.com/cli/init) or [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/) to bootstrap the example:
+
+```bash
+npx create-next-app --example with-cssed with-cssed-app
+# or
+yarn create next-app --example with-cssed with-cssed-app
+```
+
+Deploy it to the cloud with [Vercel](https://vercel.com/import?filter=next.js&utm_source=github&utm_medium=readme&utm_campaign=next-example) ([Documentation](https://nextjs.org/docs/deployment)).
