-This script is designed to help you manage and optimize Star Citizen on Linux.
+Zenity menus are used for a GUI experience with a fallback to terminal-based menus where Zenity is unavailable.  
+Command line arguments are available for quickly launching functions from the terminal.  
 
-Zenity menus are used for a GUI experience with a fallback to terminal-based menus where Zenity is unavailable. The game directory paths provided by the user on first run are saved in *$XDG_CONFIG_HOME/starcitizen-lug/*.  Keybinds are backed up to *$XDG_CONFIG_HOME/starcitizen-lug/keybinds/*
+Configuration is saved in *$XDG_CONFIG_HOME/starcitizen-lug/*.
