+## Deployment
+
+Follow the steps for [Development](#development) as above, but instead
+of `npm start` you'll want to:
+
+```sh
+> npm run build
+```

+Either configure your webserver to make the actual `build/` directory
+visible on the web, or alternatively copy it to somewhere to serve it
+from.
