+[BUILDING THE RUNKIT MODULE FOR WINDOWS]
+First, place source code of runkit into a temporary directory, for example "C:\runkit-source".
+Open your Windows SDK command prompt or Visual Studio Command prompt.
+Then change into the runkit's source code directory:
+
+C:
+cd C:\runkit-source
+
+After that, run phpize from your PHP SDK. This may be something like
+
+C:\php\SDK\phpize.bat
+
+Then configure your runkit module by executing "configure". You can view the full list of options by the command
+
+configure --help
+
+but in most cases, you probably will choose a simple command
+
+configure --enable-runkit
+
+After all run
+
+nmake
+
+Now you should have the "php_runkit.dll" file.
