 Most of the time the default Next.js server will be enough but there are times you'll want to run your own server to integrate into an existing application. Next.js provides [a custom server api](https://nextjs.org/docs/advanced-features/custom-server).
 
+The example shows a server that serves the component living in `pages/a.ts` when the route `/b` is requested and `pages/b.ts` when the route `/a` is accessed. This is obviously a non-standard routing strategy. You can see how this custom routing is being made inside `server.ts`.
+
 Because the Next.js server is a Node.js module you can combine it with any other part of the Node.js ecosystem. In this case we are using express.
 
+The example shows how you can use [TypeScript](https://typescriptlang.com) on both the server and the client while using [Nodemon](https://nodemon.io/) to live reload the server code without affecting the Next.js universal code.
+
 ## Deploy your own
 
 Deploy the example using [Vercel](https://vercel.com?utm_source=github&utm_medium=readme&utm_campaign=next-example) or preview live with [StackBlitz](https://stackblitz.com/github/vercel/next.js/tree/canary/examples/custom-server-express?runScript=dev)
