 ### 🖥️ Windows / MacOS
 The libraries included with the project only work with gcc compiler, for now, if you want to use it on Windows or macOS, you'll need to [download sfml](https://www.sfml-dev.org/download/sfml/2.5.1/) and compile the source code located in `/src` yourself.
+
+Once you have compiled the source files you can set `SFML_DIR` in `CMakeLists.txt` to the path which contains SFMLConfig.cmake. This will depend on where you have installed SFML to, for instance `C:/Program Files (x86)/SFML/lib/cmake/SFML`. From the root directory of the repository run `mkdir build cd build` and then run `cmake ..` to generate make files. For a list of generators you can type`cmake -G`. For instance if you want to build for the latest version of Visual Studio run `cmake -G 'Visual Studio 17 2022' ..` from within `/build`.
