The only reason this repo exists is to supply the necessary python 3.10 cross-platform wheels. It is a direct fork of v5.8.0 https://github.com/giampaolo/psutil at the time of writing. You are welcome to use this via pypi from https://pypi.org/project/psutil-wheels/ but there will be no support provided. 99.9% of people should continue using the official psutil. Only use this if it has a wheel for psutil that you cannot get from the official source.
