This place is an utter disaster, completely unorganized. There are much better positions out there, I recommend waiting for something else. The documentation is basically nonexistent, and what is there isn't of any use to anyone. The pay is about average for entry level techs, so you can find that, or better, literally anywhere. The difference is that you won't have to deal with the complete chaos that this place brings, and you'll miss out on some passive aggressive digs from the owner who drives a 100k+ car and pays his employees 30k a year.
Just look elsewhere, this place sucks.
