+With `CalendarCarousel<YourEventClass>` and `EventList<YourEventClass>` you can specifiy a custom Event class.
+
+## Install
+
+Add `flutter_calendar_carousel` as a dependency in pubspec.yaml
+For help on adding as a dependency, view the [documentation](https://flutter.io/using-packages/).
+
+## Usage
+
+```dart
+import 'package:flutter_calendar_carousel/flutter_calendar_carousel.dart' show CalendarCarousel;
+Widget widget() {
+  return Container(
+    margin: EdgeInsets.symmetric(horizontal: 16.0),
+    child: CalendarCarousel<Event>(
+      onDayPressed: (DateTime date, List<Event> events) {
+        this.setState(() => _currentDate = date);
+      },
+      weekendTextStyle: TextStyle(
+        color: Colors.red,
+      ),
+      thisMonthDayBorderColor: Colors.grey,
+//      weekDays: null, /// for pass null when you do not want to render weekDays
+//      headerText: Container( /// Example for rendering custom header
+//        child: Text('Custom Header'),
+//      ),
+      customDayBuilder: (   /// you can provide your own build function to make custom day containers
+        bool isSelectable,
+        int index,
+        bool isSelectedDay,
+        bool isToday,
+        bool isPrevMonthDay,
+        TextStyle textStyle,
+        bool isNextMonthDay,
+        bool isThisMonthDay,
+        DateTime day,
+      ) {
+          /// If you return null, [CalendarCarousel] will build container for current [day] with default function.
+          /// This way you can build custom containers for specific days only, leaving rest as default.
+
+          // Example: every 15th of month, we have a flight, we can place an icon in the container like that:
+          if (day.day == 15) {
+            return Center(
+              child: Icon(Icons.local_airport),
+            );
+          } else {
+            return null;
+          }
+      },
+      weekFormat: false,
+      markedDatesMap: _markedDateMap,
+      height: 420.0,
+      selectedDateTime: _currentDate,
+      daysHaveCircularBorder: false, /// null for not rendering any border, true for circular border, false for rectangular border
+    ),
+  );
+}
+```
