 --------------------------------------
 If you want to build it from source code, you can do by next steps.
 
-1.  Clone this project from github.com, then move into the project directory
+1.  Building OpenCV 2.1 requiers [CMake](http://www.cmake.org/).
+    You can easily install it by using [MacPorts](http://www.macports.org/).
+
+        % sudo port install cmake
+
+2.  Clone this project from github.com, then move into the project directory
 
         % git clone git://github.com/niw/iphone_opencv_test.git
 
-2.  Getting source code from sourceforge. I tested with [OpenCV-2.0.0.tar.bz2](http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.0/OpenCV-2.0.0.tar.bz2/download).
+3.  Getting source code from sourceforge. I tested with [OpenCV-2.1.0.tar.bz2](http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.1/OpenCV-2.1.0.tar.bz2/download).
 
-3.  Extract downloaded archive on the top of project project directory
 
-        % tar xjvf opencv-2.0.0.tar.bz2
+4.  Extract downloaded archive on the top of demo project directory
 
-4.  Apply patch for iPhone SDK
+        % tar xjvf OpenCV-2.1.0.tar.bz2
 
-        % cd OpenCV-2.0.0
-		% patch -p0 < ../cvcalibration.cpp.patch_opencv-2.0.0
+5.  Apply patch for iPhone SDK
 
-5.  Following next steps to build OpenCV static library for simulator
+        % cd OpenCV-2.1.0
+        % patch -p1 < ../OpenCV-2.1.0.patch
 
-        % cd OpenCV-2.0.0
-		% mkdir build_simulator
-		% ../../configure_opencv
-		% make
-		% make install # Install all files into ../../opencv_simulator
+6.  Following next steps to build OpenCV static library for simulator.
+    All files are installed into ``opencv_simulator`` directory.
+    When running ``make`` command, you've better assign ``-j`` option and number according to number of your CPU cores.
+    Without ``-j`` option, it takes a long time.
 
-6.  Following next steps to build OpenCV static library for device
+        % cd ..
+        % mkdir build_simulator
+        % cd build_simulator
+        % ../opencv_cmake.sh Simulator ../OpenCV-2.1.0
+        % make -j 4
+        % make install
 
-        % cd OpenCV-2.0.0
-		% mkdir build_device
-		% ARCH=device ../../configure_opencv
-		% make
-		% make install # Install all files into ../../opencv_device
+7.  Following next steps to build OpenCV static library for device
+    All files are installed into ``opencv_device`` directory.
 
-Patch and Configure support script
-----------------------------------
+        % cd ..
+        % mkdir build_device
+        % cd build_device
+        % ../opencv_cmake.sh Device ../OpenCV-2.1.0
+        % make -j 4
+        % make install
 
-OpenCV 2.0.0 (and also 1.1.0) has a glitch which refuse builing the library with iPhone SDK.
-You need to apply the patch ``cvcalibration.cpp.patch`` so that you can build it.
+Build support script
+--------------------
 
-Congiure support script ``configure_opencv`` has some options to build OpenCV with iPhone SDK.
-Try to ``--help`` option to get the all options of it.
+uild support script ``opencv_cmake.sh`` has some options to build OpenCV with iOS SDK.
+Try ``--help`` option to get the all options of it.
