+This module contains all the necessary Classes and Function used to Parse C and
+C++ code into SymPy expression
+The module serves as a backend for SymPyExpression to parse C code
+It is also dependent on Clang's AST and SymPy's Codegen AST.
+The module only supports the features currently supported by the Clang and
+codegen AST which will be updated as the development of codegen AST and this
+module progresses.
+You might find unexpected bugs and exceptions while using the module, feel free
+to report them to the SymPy Issue Tracker
+
+Features Supported
+==================
+
+- Variable Declarations (integers and reals)
+- Assignment (using integer & floating literal and function calls)
+- Function Definitions and Declaration
+- Function Calls
+- Compound statements, Return statements
+
+Notes
+=====
+
+The module is dependent on an external dependency which needs to be installed
+to use the features of this module.
+
+Clang: The C and C++ compiler which is used to extract an AST from the provided
+C source code.
