In chapter 8, we've added assets to Brushfire for the start of chapter 8. Therefore, it's necessary to clone the chapter 8 repo named brushfire-ch8-start before starting the chapter. Chapter 8 also has an ending GitHub repo named brushfire-ch8-end. If you'd like to see what the project looks like by the end of chapter 8 or you want to use it for the start of chapter 9, clone this repo.
