+# Example app with [Compiled](https://github.com/atlassian-labs/compiled) (CSS-in-JS)
+
+This example features how to use [Compiled](https://github.com/atlassian-labs/compiled) as the build time CSS-in-JS styling solution instead of [styled-jsx](https://github.com/zeit/styled-jsx).
+
+## Deploy your own
+
+Deploy the example using [Vercel](https://vercel.com?utm_source=github&utm_medium=readme&utm_campaign=next-example):
+
+[![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/new/git/external?repository-url=https://github.com/vercel/next.js/tree/canary/examples/with-compiled-css&project-name=with-compiled-css&repository-name=with-compiled-css)
+
+## 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-compiled-css with-compiled-css-app
