First steps

/lp group default permission set exyliaemotes.command.emote true

Without this /emote cannot be run at all — and a player who cannot see the catalogue cannot want anything in it.

/lp group default permission set exyliaemotes.emote.wave true
/lp group vip permission set exyliaemotes.category.meme true

One emote for everybody, a whole tab for a rank.

/emote. The tabs are down the left, the emotes beside them, and the first tab is the player's own favourites.

Left click closes the window and performs it. The player watches from the camera; any key, any click or a hit ends it.

/emotesadmin crate block add

Binds the block you are looking at, so clicking it opens the crate. The button in the menu and /emote crate open the same screen.

/emotesadmin keys give <player> 1

Every new player already starts with one (crate.start-keys). For a key they can hold, sell and give away instead, item key <player> 1.

One key, one reel. What comes out is theirs for good — see The crate.

/emote play handshake Steve

Steve has to be within duet.max-distance blocks — three by default.

Steve clicks Accept in chat, types /emote accept, or right-clicks whoever invited him.

Placed on the line between them and turned towards each other, so the hands meet in the middle.
