+Compiling under Windows using MinGW
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+It is possible to compile ioQ3 using the MinGW (Minimalist GNU for Windows)
+toolset. It's a little more involved than compiling for Linux; steps are as
+follows:
+
+1. Download and install MinGW and MSys from http://www.mingw.org/.
+2. Download http://www.libsdl.org/extras/win32/common/directx-devel.tar.gz
+   and untar in into your MinGW directory (usually C:\MinGW).
+3. Perform the usual precompilation sacrificial ritual.
+4. Open an MSys terminal, and follow the instructions for compiling on Linux.
+5. Steal underpants
+6. ?????
+7. Profit!
+
+It is also possible to cross compile for Windows using MinGW. A script is
+available to build a cross compilation environment from
+http://www.libsdl.org/extras/win32/cross/build-cross.sh. The gcc/binutils
+version numbers that the script downloads may need to be altered. After you
+have successfully run this script cross compiling is simply a case of using
+'./cross-make-mingw.sh' in place of 'make'.
