 ## Another drag and swipe library?
 
-There are a bunch of tutorials, libraries, and examples for implementing “drag & drop” and “swipe-to-dismiss” in Android, using `RecyclerView`. Many of them are still using the old `View.OnDragListener`, and [Roman Nurik’s Swipe-to-Dismiss](https://github.com/romannurik/Android-SwipeToDismiss) approach, even though there are newer (and better) methods available. A few of these solutions use the newer APIs, but often rely on `GestureDetector` and `onInterceptTouchEvent`, or the implementation is overly complex. There’s actually a really simple way to add these features to RecyclerView, and it’s part of the Android Support Library: [ItemTouchHelper](https://developer.android.com/reference/android/support/v7/widget/helper/ItemTouchHelper.html).
+This project is an example of basic drag & drop and swipe-to-dismiss with `RecyclerView` using `ItemTouchHelper`. It corresponds with an article series found here:
