 Decoding is done using a `BinaryDecoder` instance and can decode any `Decodable` type that was previously encoded using the `BinaryEncoder`. Of course you can declare `Encodable` or `Decodable` conformance by using `Codable` as well.

 ### EncodedData
 
-An intermediate representation which represents the encoded data.  This type is the direct connection between raw memory and a type that can be converted to and from a `Codable` object.
+The `BinaryEncoder.encode` method returns a type called `EncodedData` (likewise `BinaryDecoder.decode` accepts an `EncodedData` instance).   This type is the direct connection between raw memory and a type that can be converted to and from a `Codable` object.

+StickyEncoding uses this intermediate representation so that it can support many use cases from direct byte conversion to writing/reading directly to/from raw memory.
 
 When encoding of an object, the intermediate representation has already been
 encoded down to a form that can be rapidly written to memory.
