Description

I would like to have the ability to dictate the docstrings style. For example, i use NumPy style Python docstrings, but the assistant is creating Google style Python docstrings. I'm new to Sourcery, so if there is a way to do that i would love for a guide.

This is now implemented and will be in our next release
