+This mapper is for the ONVIF IP camera. For resource-limited, it's only be tested with the HIKVISION camera.
+
+Supported functions:
+- Save frame. You can define it in device-instance.yaml and save the rtsp stream as video frame files.
+- Save video. You can define it in device-instance.yaml and save the rtsp stream as video files.
+
+steps:
+
+1. Run onvif mapper 
+
+   There are two ways to run onvif mapper:
+
+a). Start locally
+- Install the dependences:
+    ```
+    sudo apt-get update && 
+    sudo apt-get install -y upx-ucl gcc-aarch64-linux-gnu libc6-dev-arm64-cross gcc-arm-linux-gnueabi libc6-dev-armel-cross libva-dev libva-drm2 libx11-dev libvdpau-dev libxext-dev libsdl1.2-dev libxcb1-dev libxau-dev libxdmcp-dev yasm
+    ```
+  and install ffmpeg with commond:
+    ```
+    sudo curl -sLO https://ffmpeg.org/releases/ffmpeg-4.1.6.tar.bz2 && 
+    tar -jx --strip-components=1 -f ffmpeg-4.1.6.tar.bz2 &&  
+    ./configure &&  make && 
+    sudo make install
+    ```
+  This may take about 5 minutes to download and build all dependencies.
+- Locally compile
+
+  You can compile and run the mapper code directly:
+    ```
+    go run cmd/main.go --v <log level,like 3> --config-file <path to config yaml>
+    ```
+b). Start using a container image
+- Build onvif mapper image:
+    ```
+    docker build -f Dockerfile_stream -t [YOUR MAPPER IMAGE NAME] .
+    ```
+  It may take about 8 minutes to build the docker image
+
+- Deploy onvif mapper container:
+
+    After successfully building the onvif mapper image, you can deploy the mapper in the cluster through deployment or other methods.
+    A sample configuration file for mapper deployment is provided in the **resource** directory.
+
+2. Build and submit the device yaml file:
+
+  After successfully deploying onvif mapper, users can build the device-instance and device-model configuration files according to the 
+  characteristics of the user edge onvif device, and execute the following commands to submit to the kubeedge cluster:
+  ```
+  kubectl apply -f <path to device model or device instance yaml>
+  ```
+
+  An example device-model and device-instance configuration file for onvif device is provided in the resource directory.
+3. View log:
+
+   Users can view the logs of the mapper container to determine whether the edge device is managed correctly.
