+The Process Idea
+---------------------
+
+Compiling Phalcon is performed as a part of PHP compilation. This is done in order to ensure, that Phalcon is built with exactly the same defines and options as PHP.
 
 Before you Begin
 ----------------
 
-Building PHP on Windows will require three things
+Building Phalcon on Windows will require four things
 
 * A properly set up build environment, including a compiler with the right SDK's and some binary tools used by the build system
 * Prebuilt libraries and headers for third party libraries that PHP uses in the correct location
-* The PHP source.

For more information on how to chose proper type or regenerate that source code (which is needed for development versions of Phalcon) read the file “build\\README.md” in the Phalcon repository.
