 Abstract
 ========
 
-This is a proposal to add Abstract Base Class support to Python 3000.
+This is a proposal to add Abstract Base Class (ABC) support to Python
+3000.  It proposes:
+
+* An "ABC support framework" which defines a metaclass, a base class,
+  a decorator, and some helpers that make it easy to define ABCs.
+  This will be added as a new library module named "abc".
+
+* Specific ABCs for containers and iterators, to be added to the
+  collections module.
+
+* Specific ABCs for numbers, to be added to a new module, yet to be
+  named.
+
+* Guidelines for writing additional ABCs.
