 ## Why?
 
 We build this package because we wanted to:
 
-- have a complete customizable slider
+- have a completely customizable slider
 - be able to swipe in every direction
-- choose our own settings for the swiper such as duration, angle, padding..
+- choose our own settings for the swiper such as duration, angle, padding, and more
-- NEW: trigger swipe, swipe left and swipe right however we want
+- trigger slide to any direction you want using the controller
-- NEW: add functions while un-/swiping, on end or when the swiper is disabled
+- add callbacks while wiping, on end or when the swiper is disabled
-- NEW: detect the direction (left, right, top, bottom) in which the card was swiped away
+- detect the direction (left, right, top, bottom) in which the card was swiped away
-
-### Detect direction of swipe
-We've added the direction in which the card was swiped away to the function ```onSwipe```. The  ```AppinioSwipeDirection``` gets now returned when the function gets called.
-
-### Trigger swipe through controller
-You can now trigger the swipe with our ```CardSwiperController```. You can call the ```swipe``` trough the controller anywhere you want. Just make sure to pass the controller to the parameter ```controller``` from our ```CardSwiper```.

 #### Controller
 
-The ```Controller``` is used to control the ```swipe```, ```swipeLeft```, ```swipeRight``` function of the swiper from outside of the widget. You can create a controller called ```CardSwiperController``` and save the instance for further usage. Please have a closer look to our Example for the usage.
