I've flipped this around, and now write the "document I want to be handed", which is precisely that condensed into just one or two pages with nothing but network paths, DNS names, service account names, Git repo names, required tooling to install, etc...

No fluff, no descriptions other than simple labels, no ten paragraph intro blurb, no index, nothing that I would normally skip over when reading someone else's document.

I call these "cheat sheets" and send them out to colleagues on their first day on a project. I've heard feedback along the lines of "I got 10x more value from that one page than three weeks of 'handover' from other people."
