 ## Usage
 
 This script accepts the following arguments:
 
-- `input_folder_path`: Path to the folder containing backup files to convert (GSM/.gsba)
-- `output_folder_path`: Path to the output folder where the converted backup folders/files are saved (Ludusavi games backups folders)
-- `--verbose`: If set, log messages will also be printed to the console
-- `backup_type`: Type of backup to process. Accepts either "gsba" or "ludusavi"
-- `--gui`: Launch the GUI
+- `--input_folder_path`: Path to the folder containing backup files to convert (GSM/.gsba). Required in non-GUI mode.
+- `--output_folder_path`: Path to the output folder where the converted backup folders/files are saved (Ludusavi games backups folders). Required in non-GUI mode.
+- `--backup_type`: Type of backup to process. Accepts either "gsba_to_ludusavi" or "ludusavi_to_gsba". Required in non-GUI mode.
+- `--verbose`: If set, log messages will also be printed to the console.
+- `--gui`: Launch the GUI.
+- `--no-gui`: Run in command-line mode.
 
 To convert from GSM to Ludusavi, use the following command:
 
 ```bash
-python main.py input_folder_path output_folder_path gsba
+python main.py --no-gui --input_folder_path <input_folder> --output_folder_path <output_folder> --backup_type gsba_to_ludusavi
 ```
 
 To convert from Ludusavi to GSM, use the following command:
 
 ```bash
-python main.py input_folder_path output_folder_path ludusavi
+python main.py --no-gui --input_folder_path <input_folder> --output_folder_path <output_folder> --backup_type ludusavi_to_gsba
 ```
 
 To launch the GUI, use the following command:
 ```bash
 python main.py --gui
-```

+## Disclaimer
+
+**Warning:** It is recommended to keep the original backup files for a while and not delete them immediately after conversion. Ensure that the converted outputs are valid by using the validation check operations provided by GameSave Manager and Ludusavi. You can also try converting the backups back and forth between the two types and verify that the initial type can be generated correctly. This will help confirm that the conversion process was successful.
