+There are two main applications, an SDL-based app (`eden-cli`) and a Qt based app (`eden`); both accept the same command line arguments.
 
 - `./eden <path>`: Running with a single argument and nothing else, will make the emulator look for the given file and load it, this behavior is similar to `eden-cli`; allows dragging and dropping games into the application.
-- `-g <path>`: Alternate way to specify what to load, overrides. However let it be noted that arguments that use `-` will be treated as options/ignored, if your game, for some reason, starts with `-`, in order to safely handle it you may need to specify it as an argument.
-- `-f`: Use fullscreen.
-- `-u <number>`: Select the index of the user to load as.
-- `-input-profile <name>`: Specifies input profile name to use (for player #0 only).
-- `-qlaunch`: Launch QLaunch.
-- `-hlaunch`: Launch homebrew launcher `nx-hbloader`.
-    - Requires a copy of Atmosphere to be extracted onto `sdmc`.
-    - This is a shorthand for `<eden folder>/sdmc/atmosphere/hbl.nsp`.
-- `-setup`: Launch setup applet.
-
