Revision Control is really important because that’s responsible for your data to be saved on the cloud and able to be downloaded if the original data is lost or if you want to upload your changes for other teammates to see and work together, think of it like google drive, you should Upload the changes every now and then, I’d recommend checking that document out when there’s some free time.
And unrelated but something I would stress heavily is to REGULARLY check in your changes with the unreal revision control, its better to be safe than sorry
