Plugins and mods
Dalamud plugins add features to Final Fantasy XIV while it runs. You install them from the Plugin Installer, which the /xlplugins chat command opens once the game is started through XIVLauncher.
Each plugin is built for one Dalamud API level. When Dalamud moves to a new level, plugins built for the previous one show (outdated) in the installer and stay off until their authors update them.
Mods from Nexus Mods replace the game’s models, textures and sounds on your own client and are loaded with Penumbra or TexTools.
