Never worked with other people? Git as a thing is off the table. Which commit? One month ago or three? Pro{gram,ject,duct}M, SME, QA, or user wants to know why? Do they even have a login to the systems they’d need? Is there search so they could find it themselves when you quit? Or you could send them a link to the docs.
