+## The idea behind the example
+
+This example shows the most basic way to use [react-ga](https://github.com/react-ga/react-ga) using `<Layout/>` component with NextJs. You can also use an HOC instead of `<Layout/>` component. Modify `Tracking ID` in `utils/analytics.js` file for testing this example.
