+# 基于 .NET 的反向代理实现
+
+## Intro
+
+基于 .NET 6 + Yarp 实现的一个简单的反向代理
+
+## 开发
+
+下载安装 .NET 6 SDK (<https://get.dot.net>)，安装好 SDK 以后，在这个目录下执行 `dotnet run` 就可以运行项目了
+
+## 部署
+
+可以使用已有的 docker 镜像进行部署
+
+``` sh
+docker run -d --name github-proxy-sample -d 9000:80 weihanli/github-proxy-sample
+```
+
+也可以自己 build 镜像部署
+
+``` sh
+# 打包镜像
+docker build -t github-proxy-sample .
+# 运行容器
+docker run -d --name github-proxy-sample -d 9000:80 github-proxy-sample
+```
+
+不使用 docker 也可以部署，可以参考文档：
+<https://docs.microsoft.com/zh-cn/aspnet/core/host-and-deploy/?view=aspnetcore-6.0>
