+# Wormhole SOCKS5 Server
+
+🚀 高性能企业级 SOCKS5 代理服务器
+
+## 快速开始
+
+### 构建和运行
+```bash
+make build
+make run
+```
+
+### 配置
+编辑 `configs/server.yaml` 来自定义服务器设置：
+
+```yaml
+proxy:
+  address: 0.0.0.0
+  port: 1080
+
+auth:
+  username: admin
+  password: your_secure_password
+```
+
+### Docker 部署
+```bash
+make docker-build
+docker run -p 1080:1080 wormhole-server:v1.0.0
+```
+
+## 功能特性
+
+### 🎯 高性能优化
