+
+```powershell
+powershell -NoProfile -ExecutionPolicy Bypass -File tools/package_release.ps1 -ExePath build/release/QtDesktopPet.exe
+```
+
+脚本会生成目录包和 zip：
+

+
+发布目录包含：
+
+```text
+QtDesktopPet.exe
+Qt runtime
+resources/characters/
+resources/icons/
+LICENSE
+README.md
+```
+
+脚本会调用 `windeployqt.exe` 收集 Qt 运行库。若当前 PATH 找不到 `windeployqt.exe`，需要指定 Qt bin 目录下的工具路径：
+
+```powershell
+powershell -NoProfile -ExecutionPolicy Bypass -File tools/package_release.ps1 `
+  -ExePath build/release/QtDesktopPet.exe `
+  -WindeployQtPath D:\Qt\6.x.x\msvcXXXX_64\bin\windeployqt.exe

+生成 Inno Setup 安装器：
+
+```powershell
+powershell -NoProfile -ExecutionPolicy Bypass -File tools/package_release.ps1 `

+  -BuildInstaller
+```
+
+安装器最终默认输出到项目根目录：
+
+```text
+QtDesktopPet-<version>-windows-x64-setup.exe
+```
+
+脚本会先让 Inno Setup 输出到当前盘符下的纯 ASCII 临时目录，例如 `D:\QtDesktopPetInstallerOutput`，再把最终安装包复制回项目根目录，避免中文项目路径下出现 `EndUpdateResource failed (5)`。如果需要改变最终安装包目录，可传入 `-InstallerOutputDir`：
+
+```powershell
+powershell -NoProfile -ExecutionPolicy Bypass -File tools/package_release.ps1 `
+  -ExePath build/release/QtDesktopPet.exe `
+  -BuildInstaller `
+  -InstallerOutputDir D:\ReleaseOutput
+```
+
+如果需要改变 Inno Setup 的临时编译输出目录，可传入 `-InstallerWorkOutputDir`。
+
+脚本默认优先查找：
+
+```text
+D:\Inno Setup 7\ISCC.exe
+D:\Inno Setup 6\ISCC.exe
+C:\Program Files (x86)\Inno Setup 7\ISCC.exe
+C:\Program Files (x86)\Inno Setup 6\ISCC.exe
+```
+
+如果 Inno Setup 安装在其他位置，可传入 `-InnoCompilerPath`。
