Guest Cheat Sheet? Card/Sign to help those with the favorites/scenes from smart switches?

Just curious if anyone has gone through the trouble to create a cheat sheet or sign for guests that come into your home. e.g. I have the same set up for switches in each bedroom, including the guest room (3x up/down controls the shades, and more). Since these guests aren’t regulars, I’m thinking of putting up a little sign next to switch with some of those less-than-obvious commands. This obviously needs to pass the look test, so I wonder if anyone else has already created a template or found something that works well.
