+## Modals
+To display a modal use ```type="modal"``` for your route components.
+Modal type inserts its 'component' after navigator component. See the ```Examples``` folder for more details.

 You can easily configure react-native-router-flux to handle a sidebar/drawer for specific routes:  
 **1.** Create a sidebar/drawer component (you can use both [react-native-drawer](https://github.com/root-two/react-native-drawer) and [react-native-side-menu](https://github.com/react-native-fellowship/react-native-side-menu)) and pass its router props to its children:
