+To display a notification message globally.
+
+## When to use
+To display a notification message at the top right of the view port. Typically it can be
+used in the following cases:
+
+- A notification with complex content.
+- A notification providing a feedback based on the user interaction. Or it may show some details
+about upcoming steps the user may have to follow.
+- A notification that is pushed by the application.
+
+## API
+
+- `notification.success(config)`
+- `notification.error(config)`
+- `notification.info(config)`
+- `notification.warning(config)`
+- `notification.warn(config)`
+- `notification.close(key: String)`
+- `notification.destroy()`
+
+The properties of config are as follows:
+
+| Property   | Description                                     | Type         | Default |
+|----------- |---------------------------------------------    | ----------- |--------|
+| message    | The title of notification box (required)        | React.Element or String      | No     |
+| description | The content of notification box (required)     | React.Element or String      | No     |
+| btn        | Custom close button                                   | React.Element      | No     |
+| key        | The unique identifer of current notification                                 | String      | No     |
+| onClose    | Specify a function that will be called after clicking the default close button  | Function    | No     |
+| duration   | A notification box is closed after 4.5s by default. When specifying `duration` to null or 0, it will never be closed automatically | Number    | 4.5     |
+
+
+`Notification` also provide a global `config()` method that can be used for specifying the default options. Once this method is used, all the notification boxes
+will take into account these globally defined options before displaying.
+

+```js
+notification.config({
+  top: 100,
+  duration: 3,
+});
+```
