 # Raylib C++ Starter
-The Raylib C++ Starter kit is a template project that provides a simple starter template for the [raylib](https://github.com/raysan5/raylib) game tools library incorporating the [raylib-cpp](https://github.com/robloach/raylib-cpp) C++ bindings and using [Make](https://www.gnu.org/software/make/) for building. The starter kit can automatcially clone down raylib and the bindings, compile them, and setup the project for build using a static library.
