-# 一键切换Ubuntu系统到简体中文
-## 这个程序有且仅在Ubuntu系统上测试过，18.04及以上应该都不会有问题，非Debian系列应该都用不了  
+## 简介
+将Linux的系统语言切换到简体中文
 
-***
+## 支持的系统
+- Debian
+- Ubuntu
+- Arch Linux
+- CachyOS
 
-## 编程语言
-C++  
-原本shell那个版本已经被彻底淘汰了，因为我从头到尾就不会bash，用cpp还能做更多设置  
-***
+## 测试通过的系统
+### **x86_64：**
+| 系统名称 | 版本 |
+| - | - |
+| Debian | 13.2 <br/> 11.6 |
+| Ubuntu | 26.04 LTS <br/> 25.10 <br/> 25.04 <br/> 24.10 <br/> 24.04.1 LTS <br/> 22.04 LTS <br/> 20.04 LTS |
+| Arch Linux | 滚动发行 |
+
+### **aarch64：**
+| 系统名称 | 版本 |
+| - | - |
+| Debian | 11.5 |
 
 ## 使用方法
-确保已经安装wget或者有其他方法可以传输文件  
+### **x86_64：**
 ```shell
-apt update && apt install -y wget
+sudo su
+wget https://github.com/TheWhiteDog9487/lag2cn/releases/latest/download/language
+chmod +x language
+./language
+rm language
 ```
-***
-下载程序
+### **aarch64：**
 ```shell
-wget https://raw.githubusercontent.com/TheWhiteDog9487/ubuntu-language-onekey-zh_cn/main/language
