Languages and menus · RoodyAbilities · Documentation

language in config.yml: the file of lang/ the server speaks (en, es, or your own: copy one as lang/<code>.yml).
per-player-language: true: each player gets messages and the menu in their Minecraft language when lang/ has it. The items always use the server language (an item looks the same for everyone).
menus/abilities.yml: where each thing of the catalogue goes, its items and your own buttons; its titles, names and lores are in lang/<language>.yml under menus.abilities.
The look of the items (item: name, lore, uses line and how each type is used) is in the lang file too.
