+## The idea behind the example
+
+This example uses [Inferno](https://github.com/infernojs/inferno), an insanely fast, 9kb React-like library for building high-performance user interfaces on both the client and server. Here we've customized Next.js to use Inferno instead of React.
+
+Here's how we did it:
+
+* Use `next.config.js` to customize our webpack config to support [inferno-compat](https://www.npmjs.com/package/inferno-compat)
