A friend recently introduced me to the ideas of creating a Manager README.
The idea is that for coworkers and new team members, you give a rundown of how you like to work and what they can expect.
Some of the canonical READMEs that are frequently used as templates can be found here.
A list of the current READMEs out in the wild (including mine), as well as some links to guides to help write them, can be found here.
You can read about my management style here.
