+How to run cairo-perf-diff on WINDOWS
+-------------------------------------
+This section explains the specifics of running cairo-perf-diff under
+win32 plateforms. It assumes that you have installed a UNIX-like shell
+environment such as MSYS (distributed as part of MinGW).
+
+ 1. From your Mingw32 window, be sure to have all of your MSVC environ-
+    ment variables set up for proper compilation using 'make'
+
+ 2. Add the %GitBaseDir%/Git/bin path to your environment, replacing the 
+    %GitBaseDir% by whatever directory your Git version is installed to.
+
+ 3. Comment out the "UNSET CDPATH" line in the git-sh-setup script 
+    (located inside the ...Git/bin directory) by putting a "#" at the 
+    beginning of the line.
+
+you should be ready to go !
+
+From your mingw32 window, go to your cairo/perf directory and run the 
+cairo-perf-diff script with the right arguments.
+
 Thanks for your contributions and have fun with cairo!
