-    cat <<EOF
-Usage: widget [target] <data> ...
-
-Update widget on device from which this function was installed with a number of content parameters that can be string, progress, icon, target, color, url or shortcut.
-
-Each argument type is derived from input, where the first argument is assumed to be a target if it matches a target configured on the widget.
-
-Progress has the form: 50% or 110/220
-
-Icon must match valid SF Symbol name such as globe or terminal.fill
-
-Colors must be hex colours such as #000 #ff00ff where the color is used for later content and 'foreground' switches back to default colour
-
-Target is used to send different content to different widgets after configuring the widgets with different target identifiers which requires the pro unlock. The target parameter is never assumed unless --target is used and is effective until next --target parameter allowing updates of several widgets with a single command
-
-URL is used when tapping the widget and is assumed for arguments starting with https:// and other schemes are supported by using --url
-
-Shortcut works like URL running the Shortcut with the given name and is never assumed without --shortcut
-
-String is the fallback type if nothing else matches, but content type can be forced for next parameter with --progress, --icon, --color, --text or --target with something like:
-  widget --text "50/100"
-
-You can update several widgets at once by using --target to send all parameters until the next --target to a particular widget. Updating several widgets at once allows more total updates per day.
