-These methods are related to the [existing SE proposal][proposal] for chunking a
-collection into subsequences of a particular size, potentially named something
-like `chunked(length:)`. Unlike the `split` family of methods, the entire

+The `chunks(of:)` takes a `size` parameter (required to be > 0) and separates 
+the collection into `n` chunks of this given size. If the size parameter is 
+evenly divided by the count of the base `Collection` all the chunks will have 
+the count equals to size. Otherwise, the last chunk will contain the remaining elements.
+
+```swift
+let names = ["David", "Kyle", "Karoy", "Nate"]
+let evenly = names.chunks(of: 2)
+// [["David", "Kyle"], ["Karoy", "Nate"]] 
+
+let remaining = names.chunks(of: 3)
+// [["David", "Kyle", "Karoy"], "Nate"]]
