 # Nkar image comparison and differences highlighting C++ API
-Nkar (armenian: նկար) is an image processing and comparison utility. The comparison of two images of the same size based on comparing each pixel of one image with the corresponding pixel of another one. After all differences are identified, algorithm generates contours (polygons) that outlines the differences. The API provides both error reporting and differences analysis. For instance results contains information on the number of difference countours generated (see usage example below).
 
-According to [stb single-file public domain libraries](https://github.com/nothings/stb) we use for image loading/decoding/saving the following image formats are supported: JPG, PNG, TGA, BMP, PSD, GIF, HDR, PIC.

 ### Installation
 
-No installation required. Just copy and compile *color.h(.cpp), image.h(.cpp), point.h(.cpp) and comparator.h(.cpp)* from the src/ directory in your project and use `nkar::Comparator` class to compare two images.
+No installation required. Just incorporate header and source files from *src/* directory
+in your project and compile them. Use `nkar::Comparator` class to compare two images.
+All library classes are in *nkar* namespace.
+
+#### Integration with `CMake` projects
+
+However, if you use `CMake` and want to integrate the library into your project
+you might want to install it first by invoking a `CMake` command from the build directory:
+
+```
+cmake --install . --prefix=<install_path> --config=Release
+```
+
+Once the library is installed you can use it from in your project by adjusting its
+`CMake` script. For example:
+
+```
+[..]
+find_package(nkar REQUIRED)
+
+add_executable(example main.cpp)
+target_link_libraries(example nkar)
+[..]
+```
 
 ### Prerequisites
 
-There are no special requirements and dependencies except *C++11* compliant compiler. The class is tested with *gcc 4.8.4* and *MSVC 12.0* (Visual Studio 2013).
-For more details see the CI badges (*Travis CI & AppVeyor CI*).
