-## Example Usage
-
-We will take simple example of a form which can be used to submit comments and then listing all comments. The example code is [available on GitHub](https://github.com/dhyey35/react-example-for-performance/blob/master/public/scripts/example.js).
-
-```javascript
-import { Component } from 'react'
-import Perf from 'react-addons-perf'
-
-const Comment = (props) => (
-	<div className="comment">
-	  <h2 className="commentAuthor">
-	    {props.author}
-	  </h2>
-	  <span>{props.children.toString()}</span>
-	</div>
- )
-//code...
-  
-ReactDOM.render(
-  <CommentBox />,
-  document.getElementById('content')
-);
-```
-Open the developer console in the browser and type `Perf.start()`. Then perform the action you want to monitor, like submitting a form. Finally, type `Perf.stop()` and `Perf.getLastMeasurements()` to get the measurements. See the Reference below for more methods.
