-react-live-route is not compatible with `react-router-dom` 4.4.0+ due to the **`this.context.router`** become it's private API(see [here](https://github.com/ReactTraining/react-router/releases/tag/v4.4.0-beta.0)). This could not be resolved by current design of `react-live-route` unfortunately. You still can use it but you need to change the version of `react-router` below 4.4.0.
-
-This project might be re-write to compatible with `react-router` 4.4.0+, to be continued 🥳.
-
 ## Caveat ⚠️
 
 - LiveRoute **SHOULD NOT** be wrapped by `Switch` directly, cause `Switch` only render the first matched child element so that LiveRoute may be skipped directly. You can move LiveRoute from `Switch` to the outside.

 ## Usage
 
-### livePath: (string | string[])
+### enhance the Route
+
+The class imported from `react-live-route` **must** be wrapped by `withRouter` to touch the property of context to work as expected.

+### Props of LiveRoute
+
+#### livePath: (string | string[])
 
 `livePath` is the path you want to hide the component instead of unmount it. The specific rules of `livePath` are the same as `path` props of Route in react-router-v4. You still can use `component` or `render` props to render a component.

 forceUnmount is funtion that return a boolean value to decide weather to forceUnmount the LiveRoute no matter it is matched or should be kept lived. 
 
 For example: when the user id equals to `27`, List page will be force unmounted while routing on other value  of id will be kept.
