There's an awful lot of things we can build that could stand a handy crib sheet, why not make it something in-game and fairly unobtrusive, so you walk up to a circuit conglomeration and there on the constant combinator is a clipboard, read it to get any notes left there. I suck at graphics so I won't attempt to draw what I'm talking about, imagine a pixelart clipboard next to the wire pad on the accumulator in this screenshot, and a clipboard icon under the circuit-details icon on its gui:

and maybe similarly for the combinators if you could find a place to put the graphic. Particularly constant combinators look to have decent-candidate spots.
For an initial implementation I'd think the text should not be accessible to mods, once everybody gets comfortable with the notion of walking up to a layout and looking around for a clipboard explaining which combinators do what and so forth maybe an additional mod-instructions text could be added but that's not the idea here.
