-# 一键切换Ubuntu系统到简体中文
-## 两个版本
-1.C++  
-2.纯Shell  
-## 不同版本区别
-这两个版本的唯一区别就是运行方式不一样，功能和结构没有任何区别  
-不信你可以去看源代码，C++版本我只是用了system函数执行shell语句，效果不能说天差地别吧，至少也能说是一模一样
-***
+## 简介
+将Linux的系统语言切换到简体中文
+
+## 支持的系统
+- Debian
+- Armbian
+- Ubuntu
+- Arch Linux
+- CachyOS
+
+## 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
-# **注意！程序运行完之后会自动重启目标电脑/服务器，请确保没有未保存的工作！否则后果自负！**
-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
 ```
-***
-下面两个版本选一个就行
-***
-下载程序(Shell)
+### **aarch64：**
 ```shell
-wget https://raw.githubusercontent.com/TheWhiteDog9487/ubuntu-language-onekey-zh_cn/main/language.sh
+sudo su
+wget https://github.com/TheWhiteDog9487/lag2cn/releases/latest/download/language_arm
+chmod +x language_arm
+./language_arm
+rm language_arm
 ```
-下载程序(C++)
+
+## 关于可用性
+对每一个系统版本进行实际测试是不现实的，我会尽量保证可用性，但是更新之后的测试只会在最新版本进行  
+并且，由于各种系统版本众多来源复杂，哪怕是最新版本也未必100%可用  
+故此，如果您在使用过程中遇到问题，请在GitHub仓库打开一个新的issue，我会尽力处理
+
+## 如果你想自行编译
+所需依赖项：
+- .NET 10 SDK
+- Clang
+- build-base或其他等效工具集
+
+推荐使用Alpine Linux进行编译，因为Alpine的系统libc就是musl，编译出的产物可以直接用而不需要管目标系统glibc的版本问题  
+您可以使用下面的Docker命令获得一个Alpine环境
 ```shell
-wget https://raw.githubusercontent.com/TheWhiteDog9487/ubuntu-language-onekey-zh_cn/main/language
+docker run --rm -it -v .:/src -w /src alpine
 ```
-运行程序(Shell)
+如果您位于中国大陆境内，推荐先对apk进行换源，以加速软件包下载
 ```shell
-sudo bash language.sh
+# https://help.mirrors.cernet.edu.cn/alpine/
+printf '%s' 'https://mirrors.cernet.edu.cn/alpine/latest-stable/main
+https://mirrors.cernet.edu.cn/alpine/latest-stable/community
+' | tee /etc/apk/repositories
 ```
-运行程序(C++)
+安装依赖项
 ```shell
-sudo chmod o+x language
-sudo ./language
-```
+apk update
+apk add --no-cache clang build-base dotnet10-sdk
+```
+然后进行编译
+```shell
+dotnet publish language.cs
+```
+你需要的ELF会出现在`artifacts/language/`文件夹内
