 Table and Collection view data sources
 ======================================
 
+## Features
+
+- [x] **O(N)** algorithm for calculating differences
+  - the algorithm has the assumption that all sections and items are unique so there is no ambiguity
+  - in case there is ambiguity, fallbacks automagically on non animated refresh
+- [x] it applies additional heuristics to send the least number of commands to sectioned view
+  - even though the running time is linear, preferred number of sent commands is usually a lot less then linear
+  - it is preferred (and possible) to cap the number of changes to some small number, and in case the number of changes grows towards linear, just do normal reload
+- [x] Supports **extending your item and section structures**
+  - just extend your item with `IdentifiableType` and `Equatable`, and your section with `AnimatableSectionModelType`
+- [x] Supports all combinations of two level hierarchical animations for **both sections and items**
+  - Section animations: Insert, Delete, Move
+  - Item animations: Insert, Delete, Move, Reload (if old value is not equal to new value)
+- [x] Configurable animation types for `Insert`, `Reload` and `Delete` (Automatic, Fade, ...)
+- [x] Example app
+- [x] Randomized stress tests (example app)
+- [x] Supports editing out of the box (example app)
+- [x] Works with `UITableView` and `UICollectionView`

 ## Why
 
 Writing table and collection view data sources is tedious. There is a large number of delegate methods that need to be implemented for the simplest case possible.
