Same for us, with two things to add:

1. Make "living documentation" part of your culture, so that the new hire feels empowered to extend and improve the documentation as they are using it to come up to speed.

2. Have proper production access controls, so that the new hire can be comfortable poking around without being afraid they can break something.

Absolutely. The whole broken window thing as well; if they see something wrong, anywhere, give them the power to change it. Everything should be versioned so there's no risk of them wiping old information out but also means they're in the habit of both creating and fixing from day one. Monday morning brain.
