+*************************************
+Porting Extension Modules to Python 3
+*************************************
+
+We recommend the following resources for porting extension modules to Python 3:
+
+* The `Migrating C extensions`_ chapter from
+  *Supporting Python 3: An in-depth guide*, a book on moving from Python 2
+  to Python 3 in general, guides the reader through porting an extension
+  module.
+* The `Porting guide`_ from the *py3c* project provides opinionated
+  suggestions with supporting code.
+* The `Cython`_ and `CFFI`_ libraries offer abstractions over
+  Python's C API.
+  Extensions generally need to be re-written to use one of them,
+  but the library then handles differences between various Python
+  versions and implementations.
