-##API Description
-
-###1) The component:
-```javascript
-<TransitionSwitch parallel={false}>
-    <Route exact path="/">
-        <Transition>home path</Transition>
-    </Route>
-    <Route path="/otherPath">
-        <Transition>other path</Transition>
-    </Route>
-    <Route path="/">
-        <Transition>other home</Transition>
-    </Route>
-    <Route path="/anotherPath">
-        <Transition>another path</Transition>
-    </Route>
-</TransitionSwitch>
-```
-
-TransitionSwitch allows to perform transitions on route change. Given its name, it works like the router v4 Switch. It
-means that only one route will be visible at all times. Except if parallel is set to true, which means that the entering
-transition won't wait for the leaving transition to be finished.
-NB: parallel may be renamed in the next revision.
-
-###2) The transitions:
-Like a switch, the children must be Route elements. The children of these route elements will be given hooks to perform
-the transition. These hooks are :
-
-```javascript
-componentWillAppear(callback)
-
-componentDidAppear()
-
-componentWillEnter(callback)
-
-componentDidEnter()
-
-componentWillLeave(callback)
-
-componentDidLeave()
-```
-The callbacks must be called after the transition is complete, in the case of animation, a good place is in the
-onComplete. The interface is very much the same as react-trasition-group v1. Meaning that componentWillAppear is called
-for the first time when the TransitionSwitch is mounted.
-
-##Sample App
-
-In case you want to quickly try it, there's a webpack setup and very rough sample app. 
-In order to build it you should run :
-```
-npm run build:example
-npm run start:server
-```
-The app will be running at localhost:8080, the build command watches for changes in case you want to play with it, the
-sources are located in src/example.
-
 
 In the next update: 
 - improve the tests
 - add warnings for uses that aren't allowed by the API.
