+The recommended properties of the menuIcon depend on the platform and type of
+an app. An icon for a watchapp should always have the size of **25x25**. For
+watchfaces on rectangular watches the icon should have the dimensions of
+**24x28**, and on round watches the icon should be **25x25**.
+
+On watches with a color display the watchface icons can be colorful! Watchapp
+icons will be translated into a 4 color grayscale icon with transparency,
+which is a great opportunity for black and white icon with antialiasing.
+
+You can add the icon in `png` format to the `resources.media` section of the
+`package.json` file, and set `"menuIcon": true`. Please note that watchapp icons
+that are larger than 25x25 will be rejected by the SDK.
