 **Output**: Creates both installer and standalone executable (`AppName-binary` on Unix, `AppName.exe` on Windows).
 
+#### [multi-instance]
+
+Allow the packaged app to run more than one instance at the same time. Default is `false`, which means launching a second instance simply focuses the existing window. Enable this when you need to open several windows of the same app simultaneously.
+
+```shell
+--multi-instance
+
+# Example: Allow multiple chat windows
+pake https://chat.example.com --name ChatApp --multi-instance
+```
+
 #### [installer-language]
 
 Set the Windows Installer language. Options include `zh-CN`, `ja-JP`, More at [Tauri Document](https://tauri.app/distribute/windows-installer/#internationalization). Default is `en-US`.

 **输出结果**：同时创建安装包和独立可执行文件（Unix 系统为 `AppName-binary`，Windows 为 `AppName.exe`）。
 
+#### [multi-instance]
+
+允许打包后的应用同时运行多个实例。默认为 `false`，此时再次启动只会聚焦已有窗口。启用该选项后，可以同时打开同一个应用的多个窗口。

+```shell

 设置 Windows 安装包语言。支持 `zh-CN`、`ja-JP`，更多在 [Tauri 文档](https://tauri.app/distribute/windows-installer/#internationalization)。默认为 `en-US`。
