Clarification on Nginx Unit ASGI

[Ahmad Ismail]

I asked After Nginx Unit, Do we still need ASGI like Uvicorn, Hypercorn,
Daphne etc <https://stackoverflow.com/q/69642063/1772898>

There one comment confused me. The comment says:

nginx unit is an ASGI compliant server; you're replacing
> uvicorn/hypercorn/daphne/etc. with nginx unit instead. It's a choice you
> make just like you'd make using either of those three or other alternatives.

I am not understanding what it means. Does it mean, I have to install both
nginx and nginx unit where nginx unit is the replacement for uvicorn /
hypercorn / daphne etc. Or, nginx unit alone can do what nginx + uvicorn /
hypercorn / daphne etc. does.

I asked the same question on FastAPI

github repo
<https://github.com/tiangolo/fastapi/issues/3128#issuecomment-947391963>.
There one part of the answer is unclear to me.

What I understood is I need to do few more things after installing nginx
unit. However, the above quote is not clear to me. Can anyone please
explain what he meant by it. And do I need to install other stuff after
installing nginx unit?
