 #### How do I access router state in a container component?
 
-React Router [provides route information via a route component's props](https://github.com/ReactTraining/react-router/blob/master/docs/Introduction.md#getting-url-parameters).

 - `go` - Moves backwards or forwards a relative number of locations in history.
 - `goForward` - Moves forward one location. Equivalent to `go(1)`

 These action creators are also available in one single object as `routerActions`, which can be used as a convenience when using Redux's `bindActionCreators()`.
