+
+## 环境要求
+
+- Docker
+- Docker Compose
+
+## 快速开始
+
+### 开发环境
+
+1. 一键启动开发环境：
+
+```bash
+make dev-start
+```
+
+这会自动：
+- 生成 proto 代码
+- 构建开发环境镜像
+- 启动所有服务
+- 显示服务状态
+
+2. 查看服务状态：
+
+```bash
+make dev-status
+```
+
+3. 查看服务日志：
+
+```bash
+make dev-logs
+```
+
+4. 停止开发环境：
+
+```bash
+make dev-down
+```
+
+### 生产环境
+
+1. 构建生产环境：
+
+```bash
+make build
+```
+
+2. 启动生产环境：
+
+```bash
+make up
+```
+
+3. 停止生产环境：
+
+```bash
+make down
+```
+
+## 其他命令
+
+### 生成 proto 代码
+
+```bash
+make gen-proto
+```
+
+### 运行测试
+
+```bash
+make test
+```
+
+## 服务端口
+
+- Nginx: 80
+- Gateway: 8080
+- User Service: 50051
+- PostgreSQL: 5432
+- Redis: 6379
+
+## 技术栈
+
+- Go 1.26.1
+- gRPC
+- PostgreSQL
+- Redis
+- Nginx
+- Docker
+
+## 注意事项
+
+- 所有服务都在 Docker 容器中运行，无宿主机依赖
+- 服务之间通过内部网络通信
+- 数据持久化使用 Docker 卷
