 Building on Windows
 -------------------
 
-Building for source on windows can be difficult.  Please see
-`matplotlib-windbuild
-<https://github.com/jbmohler/matplotlib-winbuild>`_ for detailed
-instructions, dependency source blobs, and helper scripts.
+The Python shipped from http://www.python.org is compiled with Visual Studio
+2008 for versions before 3.3 and Visual Studio 2010 for 3.3 and later.  Python
+extensions are recommended to be compiled with the same compiler.  The .NET
+Framework 4.0 is required for MSBuild (you'll likely have the requisite
+Framework with Visual Studio).  In addition to Visual Studio `CMake
+<http://www.cmake.org>`_ is required for building libpng.
+
+Since there is no canonical Windows package manager the build methods for
+freetype, zlib, libpng, tcl, & tk source code are documented as a build script
+at `matplotlib=winbuild <https://github.com/jbmohler/matplotlib-winbuild>`.
