You can find details on the Critical Flows and Test Cases in [this project's GitHub Wiki](https://github.com/10up/eight-day-week/wiki) as well as details on our overall approach to [Critical Flows and Test Cases in our Open Source Best Practices](https://10up.github.io/Open-Source-Best-Practices/testing/#critial-flows).
