-## Migrating from v1.x to v2.0
+## Migrating from v1.x to v2.x
 Version 2 is 100% API complete to version 1. However, there is a breaking change in the `onOpen` and `onClose` callbacks. These methods now fire at the end of the collapsing animation. There is also the addition of `onOpening` and `onClosing` callbacks which fire at the beginning of the animation. 
 
 To migrate to v2 from v1 simply change the `onOpen` prop to `onOpening` and `onClose` to `onClosing`.
 
-## What's new in 2.0
+# What's new in version 2.0.1

+This is a container for the content passed into the component. This keeps everything nice and neat and allows the component to do all it's whizzy calculations.
 
 If you're using a CSS framework such as Foundation or Bootstrap, you probably want to use their classes instead of styling `.Collapsible`. See Properties above.

 ## Example
-An example of the component in action is available in the example folder. To see it in action you can run `wepback-dev-server` which will run the webpack build and open the example.
