Where did I start in the codebase and why? I started off looking into app > mailers > appointment_notif. Seemed like if they wanted to change something about what was in the contents of an email sent out regarding notification that would be the place to start to see how it's currently set up. Looks like there are two messages, one for reminder and one for cancelling that can be modified.
What is familiar about the codebase? The structure of things. I expected this to live in a directory inside of app and it does. Not sure where it lives as far as controller actions calling it but I haven't started digging through controllers yet.
Are you making any assumptions? I'm assuming that this tied to users in the database, it takes two people to have a "paired" meeting. These mailers are also probably being triggered by another database post action after a paired meeting is created or destroyed.
How are you identifying what files are relevant to your issue? Started
