+If the source you download is not a link, but a git repository, you can use `-G` or `--custom-git` to rewrite the download link,
+so that the downloader can force the use of the specified git repository to download packages from this source.
+The usage method is `{source-name}:{branch}:{url}`, which can rewrite the download link of multiple libraries at the same time. 
+It is also available when downloading with the `--for-extensions` option.
+
+```bash
+# Specifying to download the source code of the PHP extension from the specified branch of the git repository
+bin/spc download --for-extensions=redis -G "php-src:master:https://github.com/php/php-src.git"
+
+# Download the latest code from the master branch of the swoole-src repository instead of PECL release version
+bin/spc download --for-extensions=swoole -G "swoole:master:https://github.com/swoole/swoole-src.git"
+```

 ## Command - doctor
 
 If you can run `bin/spc` normally but cannot compile static PHP or dependent libraries normally,

+如果你下载的资源不是链接，而是一个 Git 仓库，你可以使用 `-G` 或 `--custom-git` 重写下载链接，让下载器强制使用你指定的 Git 仓库下载此 source 的包。
+使用方法为 `{source-name}:{branch}:{url}` 即可，可同时重写多个库的下载地址。在使用 `--for-extensions` 选项下载时同样可用。

+```bash
+# 例如：下载 master 分支的 php-src
+bin/spc download --for-extensions=redis,phar -G "php-src:master:https://github.com/php/php-src.git"

 ## 命令 doctor - 环境检查
 
 如果你可以正常运行 `bin/spc` 但无法正常编译静态的 PHP 或依赖库，可以先运行 `bin/spc doctor` 检查系统自身是否缺少依赖。
