A server sends instruction screens to clients, and each screen can carry a title, a subtitle, controls, a description and sections. Controls and descriptions can embed keyboard and mouse icons drawn from a custom icon font, and text supports Minecraft chat formatting codes such as bold and red, plus inline RRGGBB hex colors. Position values are normalized screen coordinates, with 0 0 at the top-left and 1 1 at the bottom-right.

Instruction files accept several language entries, such as es and en, so each player sees content in their own language. Translations can be generated automatically through the MyMemory API, or pre-generated with a command so clients receive the text without waiting when a screen opens. Timers with a configurable countdown and cinematic sequences can run alongside a screen, and a command array can execute in order when it opens.

The mod needs Lodestone. It runs on Fabric and Forge, and the server side also works on Paper, Spigot, Bukkit and Purpur. Opening and scheduling instructions with commands requires operator permission level 2 or higher. Files are published for 1.20.1 – 1.21.1 under a custom license, and the code is not open source.
