Is there any documentation for the latest versions of ACR?

I find that the User Guide under Adobe Creative Cloud Learn & Support are way out of date. ACR has had so many changes in recent years that the documentation is mostly useless. I have been using ACR for years and (mostly) following along with the changes - I can only imagine how frustrating it must be for anyone new to ACR who consults the documentation.

Specifically I wanted to brush up my understanding of Presets and Profiles. It has been a number of years (and many versions of ACR) since I last built a default preset for my camera. And I have also been playing with creating a camera profile. So I went to the read the online documentation for these topics, and wow - it's so old it bears no resemblance to the application anymore.

If anyone knows of any 2024 relevant documentation for ACR Profiles and/or Presets I would appreciate a point in the right direction.

Thanks,
Peter
