Difference between setup.py and Python install -e ‘.[doc,test,dev]’

[marvindore]

Hello,
I would like to install backtesting.py so that I can personally use it to back test but also contribute code for bug fixes.

What is the best way to install for this workflow?
Is there a performance hit for installing for development?
Should I simply use pip install for production use case and have a local repo specifically for contributing code only?

Thanks in advance for your feedback!
