Hi,
You will have to provide as well the message dictionary that you checker
is going to emit. I just documented this here:
https://docs.pylint.org/en/latest/custom_checkers.html#writing-your-own-checker
This part needs more documentation work though, so if you notice
any other inconsistency, let me know.
