+
+            **Windows (需要 Windows 10 1809+ 或 Windows 11)**
+
+            自包含版本(推荐，无需安装 .NET 9 运行时)
+            - [64位(常用)](https://github.com/${{ github.repository }}/releases/download/${{ github.event_name == 'workflow_dispatch' && format('v{0}', github.event.inputs.version) || github.ref_name }}/iiCourseWPF-v${{ steps.version.outputs.version }}-win-x64-self-contained.zip) | [32位](https://github.com/${{ github.repository }}/releases/download/${{ github.event_name == 'workflow_dispatch' && format('v{0}', github.event.inputs.version) || github.ref_name }}/iiCourseWPF-v${{ steps.version.outputs.version }}-win-x86-self-contained.zip) | [ARM64](https://github.com/${{ github.repository }}/releases/download/${{ github.event_name == 'workflow_dispatch' && format('v{0}', github.event.inputs.version) || github.ref_name }}/iiCourseWPF-v${{ steps.version.outputs.version }}-win-arm64-self-contained.zip)
+
+            框架依赖版本(体积较小，需先安装 [.NET 9 运行时](https://dotnet.microsoft.com/download/dotnet/9.0))
+            - [64位](https://github.com/${{ github.repository }}/releases/download/${{ github.event_name == 'workflow_dispatch' && format('v{0}', github.event.inputs.version) || github.ref_name }}/iiCourseWPF-v${{ steps.version.outputs.version }}-win-x64-framework.zip) | [32位](https://github.com/${{ github.repository }}/releases/download/${{ github.event_name == 'workflow_dispatch' && format('v{0}', github.event.inputs.version) || github.ref_name }}/iiCourseWPF-v${{ steps.version.outputs.version }}-win-x86-framework.zip) | [ARM64](https://github.com/${{ github.repository }}/releases/download/${{ github.event_name == 'workflow_dispatch' && format('v{0}', github.event.inputs.version) || github.ref_name }}/iiCourseWPF-v${{ steps.version.outputs.version }}-win-arm64-framework.zip)
+
+            纯框架依赖版本(体积最小 ~200KB，需先安装 [.NET 9 运行时](https://dotnet.microsoft.com/download/dotnet/9.0))
+            - [下载](https://github.com/${{ github.repository }}/releases/download/${{ github.event_name == 'workflow_dispatch' && format('v{0}', github.event.inputs.version) || github.ref_name }}/iiCourseWPF-v${{ steps.version.outputs.version }}-dotnet9-required.zip)
+
+            ### 如何选择版本？
+
+            | 版本类型 | 文件大小 | 是否需要 .NET 9 | 适用场景 |
+            |---------|---------|----------------|---------|
+            | 自包含 64位 | ~50MB | ❌ 不需要 | **大多数用户推荐**，64位 Windows |
+            | 自包含 32位 | ~45MB | ❌ 不需要 | 32位 Windows 系统 |
+            | 自包含 ARM64 | ~45MB | ❌ 不需要 | Surface Pro X、Copilot+ PC 等 ARM 设备 |
+            | 框架依赖 64位 | ~5MB | ✅ 需要 | 已安装 .NET 9 的 64位系统 |
+            | 框架依赖 32位 | ~4MB | ✅ 需要 | 已安装 .NET 9 的 32位系统 |
+            | 框架依赖 ARM64 | ~4MB | ✅ 需要 | 已安装 .NET 9 的 ARM 设备 |
+            | 纯框架依赖 | ~200KB | ✅ 必须 | 开发者或磁盘空间极紧张 |
+
+            ### 快速开始
+
+            1. **下载对应版本**（不确定就选「自包含 64位」）
+            2. **解压**到任意文件夹
+            3. **运行** `iiCourseWPF.exe`
+
+            ### 校验
+
+            文件 SHA256 校验和可在发布页面查看，或下载 [checksums.txt](https://github.com/${{ github.repository }}/releases/download/${{ github.event_name == 'workflow_dispatch' && format('v{0}', github.event.inputs.version) || github.ref_name }}/checksums.txt)。
