 ## Environment Dependencies
 
 ### Bare mental version(UNTESTED)
+
 System requirements:  
+
 - Linux
 - Windows(may need to complie and install gmssl yourself)
 
 The project relies on the following software:  
+
 - Python 3.11
 - gmssl
 - gmssl-python
 
+### Docker installer
+
+```bash
+apt update && apt install docker.io mosh -y
+```
+
 ### Docker version
+
 docker version:  
+
 - Version:           24.0.5  
 - API version:       1.43  
 - Go version:        go1.20.6  
+
 ## Installation Steps
 
 ### Pre-installation
+
 This project depends on gmssl, so you need to compile it from source first.  
 Visit [GmSSL](https://github.com/guanzhi/GmSSL) to learn how to install.  
 
 Then install essential python libs  
+
 ```bash
 pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple
 ```
 
-
 ## Docker Installation
 
 ### Use base image and build yourself
+
 ```bash
 docker build . -f basedockerfile -t git.mamahaha.work/sangge/tpre:base
-docker pull git.mamahaha.work/sangge/tpre:base  
+(or docker pull git.mamahaha.work/sangge/tpre:base)  
 docker build . -t your_image_name
-docker run your_image_name
 ```
 
 ### Use pre-build image
+
 ```bash
 docker pull git.mamahaha.work/sangge/tpre:latest
-docker run git.mamahaha.work/sangge/tpre:latest
 ```
