+## Features:
+
+ - icon (either a widget or a menu item) can be one of:
+    - a name of an icon from [feather icons](https://feathericons.com/): `arrow-down-circle`;
+    - a path to a file: `/tmp/someicon.png;
+    - a URL pointing to the icon: `http://some-icon.online/image.png`;
+
 ## Plugins
 
 You can create your own scripts in any language, the only rule is - it should return a proper JSON.
