 To avoid the trouble of environment setup, running in a Docker container is highly recommended. Otherwise, if you work on `Ubuntu` with `root` privilege, you can still complete the installation.
 
 ### Choice 1: Running in Docker Container (Recommend)
-Docker is an open-source tool to build, ship, and run distributed applications in an isolated environment. A Docker image for this project has been provided in [hub.docker.com](https://hub.docker.com) with dependencies of cuda and cudnn installed. This Docker image requires the support of NVIDIA GPU, so please make sure its availability and the [nvidia-docker](https://github.com/NVIDIA/nvidia-docker) has been installed.
+Docker is an open-source tool to build, ship, and run distributed applications in an isolated environment. If you  do not have a Docker environment, please refer to [Docker](https://www.docker.com/). If you will use GPU version, you also need to install [nvidia-docker](https://github.com/NVIDIA/nvidia-docker).
 
-Take several steps to launch the Docker image:
-- Download the Docker image
+We provide docker images containing the latest PaddleSpeech code, and all environment and package dependencies are pre-installed. All you have to do is to **pull and run the docker image**. Then you can enjoy PaddleSpeech without any extra steps.
 
-For example, pull paddle 2.2.0 image:
-```bash
-sudo nvidia-docker pull registry.baidubce.com/paddlepaddle/paddle:2.2.0-gpu-cuda10.2-cudnn7
-```
-- Clone this repository
-```bash
-git clone https://github.com/PaddlePaddle/PaddleSpeech.git
-```
-- Run the Docker image
-```bash
-sudo nvidia-docker run --net=host --ipc=host --rm -it -v $(pwd)/PaddleSpeech:/PaddleSpeech registry.baidubce.com/paddlepaddle/paddle:2.2.0-gpu-cuda10.2-cudnn7 /bin/bash
-```
-- Enter PaddleSpeech directory.
-```bash
-cd /PaddleSpeech
-```
-Now you can execute training, inference, and hyper-parameters tuning in  Docker container.
+Get these images and guidance in [docker hub](https://hub.docker.com/repository/docker/paddlecloud/paddlespeech), including CPU, GPU, ROCm environment versions. 
+
+If you have some customized requirements about automatic building docker images, you can get it in github repo [PaddlePaddle/PaddleCloud](https://github.com/PaddlePaddle/PaddleCloud/tree/main/tekton).
 
 ### Choice 2: Running in Ubuntu with Root Privilege
 - Install `build-essential` by apt

 - 选择 2： 使用`Ubuntu` ，并且拥有 root 权限。
 
 为了避免各种环境配置问题，我们非常推荐你使用 docker 容器。如果你不想使用 docker，但是可以使用拥有 root 权限的 Ubuntu 系统，你也可以完成**困难**方式的安装。
-### 选择1： 使用Docker容器（推荐）
-Docker 是一种开源工具，用于在和系统本身环境相隔离的环境中构建、发布和运行各类应用程序。你可以访问 [hub.docker.com](https://hub.docker.com) 来下载各种版本的 docker，目前已经有适用于 `PaddleSpeech` 的 docker 提供在了该网站上。Docker 镜像需要使用 Nvidia GPU，所以你也需要提前安装好 [nvidia-docker](https://github.com/NVIDIA/nvidia-docker) 。
-你需要完成几个步骤来启动docker：
-- 下载 docker 镜像:
-  例如，拉取 paddle2.2.0 镜像：
-```bash
-sudo nvidia-docker pull registry.baidubce.com/paddlepaddle/paddle:2.2.0-gpu-cuda10.2-cudnn7
-```
-- 克隆 `PaddleSpeech` 仓库
-```bash
-git clone https://github.com/PaddlePaddle/PaddleSpeech.git
-```
-- 启动 docker 镜像
-```bash
-sudo nvidia-docker run --net=host --ipc=host --rm -it -v $(pwd)/PaddleSpeech:/PaddleSpeech registry.baidubce.com/paddlepaddle/paddle:2.2.0-gpu-cuda10.2-cudnn7 /bin/bash
-```
-- 进入 PaddleSpeech 目录
-```bash
-cd /PaddleSpeech
-```
+### 选择1： 使用 Docker 容器（推荐）
+Docker 是一种开源工具，用于在和系统本身环境相隔离的环境中构建、发布和运行各类应用程序。如果您没有 Docker 运行环境，请参考 [Docker 官网](https://www.docker.com/)进行安装，如果您准备使用 GPU 版本镜像，还需要提前安装好 [nvidia-docker](https://github.com/NVIDIA/nvidia-docker) 。 
+
+我们提供了包含最新 PaddleSpeech 代码的 docker 镜像，并预先安装好了所有的环境和库依赖，您只需要**拉取并运行 docker 镜像**，无需其他任何额外操作，即可开始享用 PaddleSpeech 的所有功能。
+
+在 [Docker Hub](https://hub.docker.com/repository/docker/paddlecloud/paddlespeech) 中获取这些镜像及相应的使用指南，包括 CPU、GPU、ROCm 版本。
+
+如果您对自动化制作docker镜像感兴趣，或有自定义需求，请访问 [PaddlePaddle/PaddleCloud](https://github.com/PaddlePaddle/PaddleCloud/tree/main/tekton) 做进一步了解。
 完成这些以后，你就可以在 docker 容器中执行训练、推理和超参 fine-tune。
 ### 选择2： 使用有 root 权限的 Ubuntu
 - 使用apt安装 `build-essential`
