+PicoBot
+
+## 快速开始
+
+1. 双击 start-gateway.vbs 启动服务
+2. 浏览器打开 http://127.0.0.1:19876
+
+## 首次使用
+
+1. 先配置 API Key，在命令行执行：
+   picobot.exe init
+2. 按提示输入 Provider 类型、API Key、模型名称
+3. 配置保存在 %USERPROFILE%\.picobot\config.yaml
+
+## 命令行
+
+    picobot.exe gateway             启动服务端（默认 127.0.0.1:19876）
+    picobot.exe gateway --port 8080 指定端口
+    picobot.exe agent               连接远程 Gateway
+    picobot.exe init                重新配置
+
+## 后台运行
+
+- 双击 start-gateway.vbs -- 完全无窗口
+- 双击 start-gateway.bat -- 可看到启动状态
