+## CI 自动构建和发布
+
+仓库提供了 Gitea Actions 工作流：
+
+```text
+.gitea/workflows/build-windows-release.yml
+```
+
+触发方式：
+
+- 推送到 `main` 分支。
+- 推送 `v*` 标签，例如 `v1.0.0`。
+- 在 Gitea 页面手动运行 `workflow_dispatch`。
+
+CI 会在 Fedora 容器中安装 MinGW-w64、Qt6、OpenCV，交叉编译 Windows x64 程序，然后打包：
+
+```text
+QtOpenCVImageTool-windows-x64-<version>.zip
+QtOpenCVImageTool-windows-x64-<version>.zip.sha256
+```
+
+最后通过 Gitea API 上传到仓库 Release。为了允许上传 Release，请在仓库的 Actions Secrets 中配置：
+
+```text
+RELEASE_TOKEN=<具有仓库 release 写权限的 token>
+```
+
+如果 Gitea 已经给 Actions 提供可写的 `GITHUB_TOKEN`，也可以不配置 `RELEASE_TOKEN`。
+
+发布版本建议使用 tag：
+
+```bash
+git tag v1.0.0
+git push origin v1.0.0
+```
+
+这样 Release 名称和包名会使用 `v1.0.0`。如果只是推送到 `main`，CI 会创建预发布版本，名称类似 `build-提交哈希`。
+
 ## WSL 中交叉编译 Windows 程序
 
 WSL 里不能使用 Linux 版 Qt/OpenCV 直接生成 Windows exe，必须准备 Windows 目标库。推荐使用 MinGW-w64 作为交叉编译器，并准备同为 MinGW-w64 目标的 Qt 和 OpenCV。
