 ## Usage
 
 ### react.js
 
-In order to use React client-side in your application, you must make sure the browser requests it. One way to do that is to drop `react.js` into `app/assets/javascript/` and by default your application manifest will pick it up. There are downsides to this approach, so we made it even easier. Once you have `react-rails` installed, you can just add a line into your config file (see Configuring) and require react directly in your manifest:

-files come from different releases. To achieve that, you have to manually replace either of them in your app.
