+## GitHub Actions Build
+
+Building the Windows version of static-php from Actions is now supported.
+Like Linux and macOS, you can enter the [Extension List](./extensions) to select the extension to be compiled, and then visit [CI on Windows](https://github.com/crazywhalecc/static-php-cli/actions/workflows/build-windows-x86_64.yml) and select the PHP version, 
+fill in the extension list (comma separated), and click Run.

+If you're going to develop or build locally, please read on.

+## GitHub Actions 构建
+
+现在已支持从 Actions 构建 Windows 版本的 static-php 了。
+和 Linux、macOS 一样，你可以进入 [扩展列表](./extensions) 选择要编译的扩展，然后 [CI on Windows](https://github.com/crazywhalecc/static-php-cli/actions/workflows/build-windows-x86_64.yml) 选择 PHP 版本、填入扩展列表（逗号分割），点击 Run 即可。

 ## 环境准备
 
 在 Windows 上构建静态 PHP 所需要的工具与 PHP 官方的 Windows 构建工具是相同的。你可以阅读 [官方文档](https://wiki.php.net/internals/windows/stepbystepbuild_sdk_2)。
