 ### Windows 10
 
-对于使用 Windows 10 的系统，在系统右下角托盘 Docker 图标内右键菜单选择 `Settings`，打开配置窗口后左侧导航菜单选择 `Daemon`。在 `Registry mirrors` 一栏中填写加速器地址 `https://dockerhub.azk8s.cn`，之后点击 `Apply` 保存后 Docker 就会重启并应用配置的镜像地址了。

 ### macOS
 
-对于使用 macOS 的用户，在任务栏点击 Docker Desktop 应用图标 -> Perferences... -> Daemon -> Registry mirrors。在列表中填写加速器地址 `https://dockerhub.azk8s.cn`。修改完成之后，点击 `Apply & Restart` 按钮，Docker 就会重启并应用配置的镜像地址了。
