 Beniget is a collection of Compile-time analyse on Python Abstract Syntax Tree(AST).
 It's a building block to write static analyzer or compiler for Python.
 
-Beniget relies on `gast <https://pypi.org/project/gast/>`_ to provide a cross
-version abstraction of the AST, effectively working across all Python 3 versions greater than 3.6.
+Beniget is compatible with the standard library AST as well as the AST generated by `gast <https://pypi.org/project/gast/>`_,
+which is a cross version abstraction of the AST.

 - ``beniget.DefUseChains`` that maps each node to the list of definition points in that node;
 - ``beniget.UseDefChains`` that maps each node to the list of possible definition of that node.
 
+Alternatives working with standard library AST: 
+
+- ``beniget.standard.Ancestors`` that maps each node to the list of enclosing nodes;
+- ``beniget.standard.DefUseChains`` that maps each node to the list of definition points in that node;
+- ``beniget.standard.UseDefChains`` that maps each node to the list of possible definition of that node.
