 - In order to push  server status to your portable device without opening ServerBox app (Such as **message push** and **home widget**), you need to install [ServerBoxMonitor](https://github.com/lollipopkit/server_box_monitor) on your servers, and config it correctly. See [wiki](https://github.com/lollipopkit/server_box_monitor/wiki) for more details.
 - **Common issues** can be found in [app wiki](https://github.com/lollipopkit/flutter_server_box/wiki).
