-There are two main applications, an SDL-based app (`eden-cli`) and a Qt based app (`eden`); both accept command line arguments and share almost the same accepted arguments.
+There are two main applications, an SDL-based app (`eden-cli`) and a Qt based app (`eden`); both accept command line arguments.
 
 ## eden
 
 - `./eden <path>`: Running with a single argument and nothing else, will make the emulator look for the given file and load it, this behaviour is similar to `eden-cli`; allows dragging and dropping games into the application.
-- `--hlaunch`: Launch homebrew launcher `nx-hbloader`.
+- `-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.
-- `-q/--qlaunch`: Launch QLaunch.
-- `-d/--debug`: Enter debug mode, allow gdb stub at port `1234`
-- `-c/--config`: Specify alternate configuration file.
-- `-f/--fullscreen`: Set fullscreen.
-- `-h/--help`: Display help.
-- `-g/--game`: 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.
-- `-m/--multiplayer`: Specify multiplayer options.
-- `-p/--program`: Specify the program arguments to pass (optional).
-- `-u/--user`: Select the index of the user to load as.
-- `-v/--version`: Display version and quit.
-- `-i/--input-profile`: Specifies input profile name to use (for player #0 only).
-- `-n/--null-render`: Forces the usage of the "Null" render backend irrespective of settings.
-- `-x/--filter`: Sets the debug log filter irrespective of settings.
-- `-s/--singlecore`: Forces single-core regardless of settings.
-- `-l/--log-file`: The file for storing the room log.
-- `-H/--headless`: Force headless mode (no GUI). Currently only used for rooms.
+- `-setup`: Launch setup applet.
 
-Room settings:
-- `-N/--name`: The name of the room.
-- `-D/--description`: The room description.
-- `-S/--bind-address`: The bind address for the room.
-- `-P/--port`: The port used for the room.
-- `-M/--max-members`: The maximum number of players for this room.
-- `-W/--password`: The password for the room.
-- `-G/--preferred-game`: The preferred game for this room.
-- `-I/--preferred-game-id`: The preferred game-id for this room.
-- `-U/--username`: The username used for announce.
-- `-T/--token`: The token used for announce.
-- `-A/--web-api-url`: yuzu Web API url.
-- `-B/--ban-list-file`: The file for storing the room ban list.
-- `-h/--help`: Display this help and exit.
-- `-v/--version`: Output version information and exit.,
+## eden-cli
 
-If the name and description of the room is specified, then it will default to headless mode if not already specified.
-
-Old settings `-hlaunch`, `-qlaunch` and `-setup` are recognized independently. They're kept for backwards compatibility with shortcuts made before the change. Using one of these makes the parser immediately halt and ignore every other option.
+- `--debug/-d`: Enter debug mode, allow gdb stub at port `1234`
+- `--config/-c`: Specify alternate configuration file.
+- `--fullscreen/-f`: Set fullscreen.
+- `--help/-h`: Display help.
+- `--game/-g`: Specify the game to run.
+- `--multiplayer/-m`: Specify multiplayer options.
+- `--program/-p`: Specify the program arguments to pass (optional).
+- `--user/-u`: Specify the user index.
+- `--version/-v`: Display version and quit.
+- `--input-profile/-i`: Specifies input profile name to use (for player #0 only).
+- `--null-render/-n`: Forces the usage of the "Null" render backend irrespective of settings.
+- `--filter/-x`: Sets the debug log filter irrespective of settings.
+- `--singlecore/-s`: Forces single-core regardless of settings.
