 #### 七、自动调节帧率
 如果要使得构建出的应用能够自动调节帧率，请打开Project Settings，将构建目标平台对应的Quality选项卡中的V Sync Count设置为Don't Sync。
-默认的逻辑是在界面静止时将帧率降低为25，在界面变动时将帧率提高至60。
-如果您需要修改帧率升高或降低时的行为，请将`Window.onFrameRateSpeedUp`和/或`Window.onFrameRateCoolDown`设置为您自己的函数。
+默认的逻辑是在界面静止时将帧率降低，在界面变动时再将帧率提高至60。
+如果您不想开启该功能，请将`Window.onFrameRateSpeedUp`和/或`Window.onFrameRateCoolDown`设置为空函数，()=> {}即可。
+
+在Unity 2019.3版本及以上，UIWidgets将使用OnDemandRenderAPI来实现帧率调节，它将在不影响UI响应速度的情况下大幅降低耗电和发热问题。
 
 #### 八、WebGL Canvas分辨率调整插件
 因为浏览器中Canvas的宽高和其在显示器上的像素数可能不一致，所以构建出的WebGL程序中画面可能会模糊。
 
 我们提供了一个包装好的`UnityObjectDetector`组件以及`onRelease`回调函数，借此您可以实现简单地将物体（例如Hierarchy内的场景物体、Project窗口下的文件等）拖拽至区域内，来获得`UnityEngine.Object[] `类型的引用并进行操作。
 
-你可以在“UIWidgetsTests -> Drag&Drop”下找到简单的实例样例。

 #### Automatically Adjust Frame Rate
 
 To build an App that is able to adjust the frame rate automatically, please open Project Settings, and in the Quality tab, set the "V Sync Count" option of the target platform to "Don't Sync".
-The default logic is to set the frame rate to 25 when the screen is static, and change the frame rate to 60 whenever the screen changes.
-If you would like to modify the behavior of speeding up or cooling down the frame rate, please set `Window.onFrameRateSpeedUp` and/or `Window.onFrameRateCoolDown` to your own functions.
+The default logic is to reduce the frame rate when the screen is static, and change it back to 60 whenever the screen changes.
+If you would like to disable this behavior, please set `Window.onFrameRateSpeedUp` and/or `Window.onFrameRateCoolDown` to null function, i.e., () => {}.
+
+Note that in Unity 2019.3 and above, UIWidgets will use OnDemandRenderAPI to implement this feature, which will greatly save the battery.
 
 #### WebGL Canvas Device Pixel Ratio Plugin
 The width and height of the Canvas in browser may differ from the number of pixels the Canvas occupies on the screen.
 
 With the provided packaged stateful widget `UnityObjectDetector` and its `onRelease` callback function, you can easily drag some objects (for example GameObject from Hierarchy, files from Project Window, etc) into the area, get the UnityEngine.Object[] references and make further modification.
 
-Please refer to "UIWidgetsTests -> Drag&Drop" for simple examples.

-You can also try UIWidgets-based Editor windows by clicking **UIWidgetsTest** on the main menu
+You can find many UIWidgets sample projects on Github, which covers different aspects and provide you
+learning materials in various levels:
+* UIWidgetsSamples (https://github.com/UIWidgets/UIWidgetsSamples). These samples are developed by the dev team in order to illustrates all the features of 
+UIWidgets. Clone this Repo to the **Assets** folder of your local UIWidgets project and then
+you can find all the sample scenes under the **Scene** folder.
+You can also try UIWidgets-based Editor windows by clicking the new **UIWidgetsTests** tab on the main menu

 The develop team is still working on the UIWidgets Wiki. However, since UIWidgets is mainly derived from Flutter,
