+## Building
+The repository contains a CMakeLists.txt to be used with [CMake](https://cmake.org).
+
+Use it to generate a platform-specific build configuration for building all examples. It should work with different compilers on Windows and Linux (C++11 required).
+
+All required headers and libs are included in the repository, building the examples should work out of the box.

-*todo* : In progress
-The repository contains CMake files for all demos and all required headers to compile the example, so any platform that supports CMake and has a C++11 compatible compiler should work.
