+## Gnome Desktop Notifications
+* **Source**: n/a
+* **Icon Support**: Yes
+* **Message Format**: Text
+* **Message Limit**: 250 Characters per message
+
+Display notifications right on your Gnome desktop.  This only works if you're sending the notification to the same system you're currently accessing.  Hence this notification can not be sent from one PC to another.
+
+### Syntax
+There are currently no options you can specify for this kind of notification, so it's really easy to reference:
+* **gnome**://
+
+
+### Parameter Breakdown
+There are no parameters at this time.
+
+#### Example
+Assuming we're on an OS that allows us to host the Gnome Desktop, we can send a notification to ourselves like so:
+```bash
+# Send ourselves a Gnome desktop notification
+apprise gnome://
+```
