The starter code distributed as part of this project is totally optional, and it's really designed to remove some of the boilerplate so you can write the code that matters for this course. That being said, it is kinda hefty, so this page serves as a brief walkthrough of what you get.
If you want to use the starter code, maybe start by trying it, and come back here only if you're confused.
