Process Journal
Your process journal (journal.md or journal.pdf) is a file that is included inside your Github pull request. It should demonstrate how you approached understanding the problem, navigated the codebase for comprehension, and iteratively write, test, and debug code to arrive at the solution. You can submit your process journal in either Markdown (journal.md) or PDF (journal.pdf) format.
