python package management confusion

Mon Jan 14 09:54:28 EST 2019

Hi,
I am a newbie completely confused with python package management.
I have a setup.py file (listed below) and have setup pip and setup.cfg to install my own dependencies from a local devpi repository.
Can setup.py reference a git repository so that I can install from that url?
Is this possible in newer versions of setuptools? Does anyone have any examples? 
Completely confused with managing packages in python....
Kind regards
