+## Presets
+
+Presets let you save named mod selections and switch between them without manually toggling mods each time. Useful for different game modes (milsim, antistasi, casual, etc.).
+
+- **Tab / Shift+Tab** — quickly cycle between presets from the main screen
+- **T** — open the Preset Manager to create, rename, delete, or overwrite presets
+
+Existing configs are automatically migrated — your current mod selection becomes the "Default" preset.
+
 ## Config
 The application creates a config file which looks like this:
 
 - Windows: `~/arma3-mod-launcher-console-config.json`
-- Linus & MacOS: `~/.config/arma3-mod-launcher-console/config.json`
+- Linux & macOS: `~/.config/arma3-mod-launcher-console/config.json`
