Left a couple of suggestions for typos and shorter sentences.

Looks good to me, but as per comment, I wonder if we need to also document a need to also provide an ILoggerService implementation too?

Removing approval as realised more work is needed.

Hi @Migaroez

Is it correct, that this is for Umbraco 14? That version is no longer supported and considered EOL, right? 🤔

Oops sorry, that was a mistake in the description.

I've made the updates raised in my first review and aligned with the latest code, that is now merged in and scheduled for 16.2.

As such approving this, so it's ready for docs team review and can be merged and published along with the release of the 16.2 release candidate (due 21st August).
