-Depth sensors compatible with Intel Perceptual Computing SDK are supported through VideoCapture
+Depth sensors compatible with Intel® RealSense SDK are supported through VideoCapture
 class. Depth map, RGB image and some other formats of output can be retrieved by using familiar
 interface of VideoCapture.
 
 In order to use depth sensor with OpenCV you should do the following preliminary steps:
 
--#  Install Intel Perceptual Computing SDK (from here <http://www.intel.com/software/perceptual>).
+-#  Install Intel RealSense SDK 2.0 (from here <https://github.com/IntelRealSense/librealsense>).
 
--#  Configure OpenCV with Intel Perceptual Computing SDK support by setting WITH_INTELPERC flag in
-    CMake. If Intel Perceptual Computing SDK is found in install folders OpenCV will be built with
-    Intel Perceptual Computing SDK library (see a status INTELPERC in CMake log). If CMake process
-    doesn't find Intel Perceptual Computing SDK installation folder automatically, the user should
-    change corresponding CMake variables INTELPERC_LIB_DIR and INTELPERC_INCLUDE_DIR to the
-    proper value.
