 Paddle Serving支持使用百度昆仑芯片进行预测部署。目前支持在百度昆仑芯片和arm服务器（如飞腾 FT-2000+/64）, 或者百度昆仑芯片和Intel CPU服务器，上进行部署，后续完善对其他异构硬件服务器部署能力。
 
+## 安装Docker镜像
+我们推荐使用docker部署Serving服务，在xpu环境下可参考[Docker镜像](Docker_Images_CN.md)文档安装xpu镜像，并进一步完成编译、安装和部署等任务。
+
 ## 编译、安装
 基本环境配置可参考[该文档](Compile_CN.md)进行配置。下面以飞腾FT-2000+/64机器为例进行介绍。

+## Install docker images
+We recommend using the docker deployment service. In the xpu environment, you can refer to the [Docker image document](Docker_Images_EN.md) to install the xpu image, and further complete tasks such as construction, installation, and deployment.

 ## Compilation and installation
 Refer to [compile](./Compile_EN.md) document to setup the compilation environment. The following is based on FeiTeng FT-2000 +/64 platform.
