 Frequently Asked Questions
 --------------------------
 
+### How do I return extra data from the render server?
+
+You can edit the render server's code and annotate the returned payload with whatever data 
+that you like. The payload provided by the render server is available under the `data` attribute 
+of the response object.
+
+For example:
+
+```python
+from react.render import render_component
+
+rendered = render_component('path/to/component.js')
+
+print(rendered.data)
+```

 Running the example
 ===================
 
-As mentioned in the ***Using React on the front-end*** section, [Webpack](https://webpack.github.io/) is used to bundle the respective js files into `dist.js` and included in `index.html`. To make React attributes like `onClick` etc. work, the app has to be re-rendered (along with all the props passed down) when it loads on the browswer. React is intelligent enough to not re-paint the browser and only update the changes, thus adding all the component properties.

 In this example, the basic_rendering example is modified to submit the Comment Form through ajax and update the Comment List by fetching the updated comments and rendering the application with new props.
