Anyhow, the volunteer-notes for the "You are here" puzzle had: Set up instructions, maintenance instructions (though I still managed to get confused on this part), a solution walk-through, suggested hints, and some "rules" (e.g., is it OK if teams touch the puzzle installation?).
I haven't kept any Shinteki volunteer notes, but if I remember correctly, I don't think they talk about the puzzle. I guess that it's OK if the volunteer's an ignoramus, LEON's automated hint system could pick up the slack. (Or maybe there are instructions about how the puzzle works, but I haven't paid attention because I'm a "second weekend" volunteer.) I mostly remember logistics: where and when to be in place. Call in when first team shows up, call in when first team leaves (to warn the next station). Call in when last team leaves. Keep track of teams and times.
