The "How to pair with a junior developer" section is extremely considerate, and highlights some behaviours that I know I've subconsciously engaged in that may have negatively impacted a junior dev. Expanding this section would be great.
I think 5 or 10 years ago I would have shut them down - I was much more arrogant back then. Instead in the next few days this person is going to demo something they've built since they are pretty much our team's expert in this tech - since none of the others have used it. If everything checks out, this could very well be our next large architectural shift - and that's incredibly awesome contribution for someone new. Even if it means he'll be putting in a lot of extra work and time - in my eyes that's better than turning him into a robot that wants to check out exactly at 5pm.
Another great section would be how to identify a pairing that is less than ideal / problematic.
