Location of Companion Guide documents for webinars

I just finished watching the latest webinar on Historian and they mentioned a Companion Document with a lot of useful information around benchmarks and best practices for using Historian.
I’ve navigated all around Inductive Automation website and resources section but cannot see anything like what was mentioned.


Is this something you can only see when watching the webinar live? I was only able to watch the recorded version.

Cheers
