-## Contributions
+With the implementation of the `setDaysState` method, developers can dynamically modify which days are selected within their application's code, even after the `SelectWeekDays` widget has already been constructed. 
+By utilizing the Global Key that is passed into the widget, one can easily update the selected dates as desired.

 Contributions of any kind are more than welcome😊! Feel free to fork and improve `day_picker` or open an issue.
