+The addon works for both Windows and Mac. Full setup instructions can be found [here](https://github.com/gallagher-tech/ofxGAkit).
 
 In this case, openFrameworks provides the windowing and rendering system (`glfw / openGL`), and automatically includes the necessary `nlohmann::json` and `glm` libraries.
 
 ### Bring Your Own Backend
 
 We aim to make `GA::kit` "framework agnostic". This means that we would like it to play nicely with other C++ creative coding frameworks like Cinder - or it could be used on its own by including a few supporting libraries.
 
-The only requirements beyond C++11 are including the `glm` and `nlohmann::json` libraries, and adding an openGL windowing library, like `glfw`.
