 # XMapLib
 A closer to the metal library for Xbox controller to keyboard and mouse input.
 
+<p>XMapLibSharp is a C# .NET GUI project using the C++ project code through a DLL via managed/native interop. With this approach,
+the project has access to the entire .NET framework for GUI work while keeping the native performance and power of the C++ XMapLib code.
