Newbie: MacOS config question

I know very little about HA but I’ve installed it (sort of) and I obviously have a misconfigured something or other.

I have tracked down ~/.homeassistant/configuration.yaml and it’s mostly empty.

I have also tracked down ~/homeassistant/lib/python3.7/site-packages and it contains all the ‘integrations’ that I need to use.

How do I enable access to site-packages for the application?
