+
+### Android
+
+Send single notification with the following command.

+```
+
+* `-m`: Notification message.
+* `-k`: [Google cloud message](https://developers.google.com/cloud-messaging/) api key
+* `-t`: Device token.
+
+### iOS
+
+Send single notification with the following command.
+
+```bash
+$ ./gopush -ios -m="your message" -i="API Key" -t="Device token"
+```

+* `-m`: Notification message.
+* `-i`: Apple Push Notification Certificate path (`pem` file).
+* `-t`: Device token.
