How to use PyCharm as a GIT diff tool from the command line?

On the PyCharm Help Website I see you can use PyCharm as a diff tool from the Command Line to compare two files. That’s awesome! However is there a way to take it a step further and use it as a git diff tool.

So I can just type pycharm diff and get the GIT differences same way you would if you were on PyCharm have setup the GIT integration and press CTRL + D to see the differences.
