+## Implementing main callbacks for other languages
+
+If you're writing language bindings for SDL and want to provide the main
+callback functionality, you should call SDL_EnterAppMainCallbacks() and pass it
+the arguments and callback functions that you want called during the program
+execution. This function will call the init, event, and iterate functions and
+then once the application is done, will call the quit callback and return.
