 What is PyPy?
 ==============
 
-PyPy 1.0
-================
+PyPy is:
+
+* A fun and challenging  open source project with many contributions
+
+* An open source implementation of Python  (written in Python)
+
+* A tool-chain with a *new paradigm* for building interpreters
 
+From Dec 2004 to March 2006 PyPy was a research project,
+funded by the EU and a consortium of companies.

+Motivation
+=============
+
+Conventional approaches to interpreters face hard trade-offs:
+speed, maintainability, flexibility.
+
+A lot of decisions are hard-coded pervasively, improvements
+and evolution are hampered (e.g. psyco, stackless require quite some efforts
+and cannot bring their full potential).
+
+Lots of duplication of effort to cover many platforms.
+
+*It should be possible to do better.*

+- *JIT compiler generator working on the Python interpreter*
+- more optimizations
+- CLI backend produces a PyPy.NET which can interact with CLR libraries
+- taint object space and transparent proxies
+
+*Not completely mature yet but our original vision is fully
+materialized*
