-This library comprises of serializers that both read and write from files and streams to the dedicated models as well as convert to and from the common internal models. This library is partially used by the current parsing and writing code but none of the internal model serialization is used.

-## Interfaces
+## InfoPrint
 
-Below is a table representing the various conversion interfaces that are implemented within this library.
+**InfoPrint** is a reference implementation for the deserialization and printing features of the library, packaged as a standalone executable for all supported platforms. It will attempt to detect and display information about many supported file types, optionally both hashing the file and outputting the information to a JSON file.
 
-| Interface Name | Source Type | Destination Type |
-| --- | --- | --- |
-| `IByteDeserializer` | `byte[]?` | Model |
-| `IByteSerializer` | Model | `byte[]?` |
-| `IFileDeserializer` | `string?` path | Model |
-| `IFileSerializer` | Model | `string?` path |
-| `IModelSerializer` | Model | Model |
-| `IStreamDeserializer` | `Stream?` | Model |
-| `IStreamSerializer` | Model | `Stream?` |
-| `IStringDeserializer` | `string?` representation | Model |
-| `IStringSerializer` | Model | `string?` representation |
