Im at the Hunter Valley stage, I feel the code used in this stage should be explained a bit more. There is no explanation of what the “step” parametre used in the functions is. Also there is used different brackets  in this stage, which is not explained. I can’t remember += has been used before and routeIndex.
I haven’t focused that much on completing the stage as I rather understand every detail about the code first.
Maybe im just stupid I don’t know, but I feel like an introduction to some of the things would be great.
