Get it up and running in a dev environment and start inserting changes to see what breaks where.

Revert and retry until you’ve learned where you’re supposed to be meddling.

Another big advantage of getting a dev environment setup is if you can get step by step debugging in place as well. You can then use that to follow the trail of a user action from the UI triggers all the way down.
