Hey @npetruzzelli !

Thanks for your PR.

Async configurations are already documented as per #3761.

I am closing this PR, but please tell me if I am missing something.

@jginsburgn - I didn't think to look for the other PR's content when I rebased and updated the example. The important thing is that users have access to the information. As long as they aren't confused, then its a win.

It doesn't have to be as verbose as something I'd write to work. My personal opinion on promise vs async didn't make @nicojs 's work any less correct and isn't something I'd want to hold up either PR.

I'm sorry it took 10 days to respond in any form. Life, both in and out of work, hasn't given me a lot of time to respond quickly.

I don't think you missed anything. No objections to the closing of the PR.
