 以一个最常见的例子说明OpenP2P如何使用：远程办公，在家里连入办公室Windows电脑。  
 相信很多人在疫情下远程办公是刚需。
 1. 先确认办公室电脑已开启远程桌面功能（如何开启参考官方说明https://docs.microsoft.com/zh-cn/windows-server/remote/remote-desktop-services/clients/remote-desktop-allow-access）
 2. 在办公室下载最新的[OpenP2P](https://gitee.com/tenderiron/openp2p/releases/),解压出来,在命令行执行
    ```
-   openp2p.exe -d -node OFFICEPC1 -user USERNAME1 -password PASSWORD1  
+   openp2p.exe install -node OFFICEPC1 -user USERNAME1 -password PASSWORD1
