-CppSharp is a collection of libraries for working with C++ code from
-high-level languages.
+CppSharp is a tool and set of libraries to turn existing native C/C++ libraries
+into libraries that can be consumed by other languages (such as C#).
 
-It has multiple use cases, from parsing C++ code to automatically generating
-bindings for wrapping C/C++ native code allowing interoperability with
-high-level languages. The supported target languages at present are C#
-(hence the name of the project) and C++/CLI.
+It is a tool that takes C/C++ header and library files and generates the 
+necessary glue to surface the native API as a managed API. Such an API can be
+used to consume an existing native library in your high-level code or add
+scripting support to a native codebase.

+It can also be used as a library to parse native code into a syntax tree with a
+rich declaration and type information model.
