 ## Usage
-Run the script with the path to the image you want to split as an argument:
 
+### As Windows Executable
+You can run the program with either the path to a single image you want to split or a directory containing multiple images.
+
+#### Single Image Mode
 ```sh
-python main.py path_to_your_image.jpg
+main.exe --image_path path_to_your_image.jpg
+```
+The program will create two new images in the "left" and "right" directories with the suffixes _left and _right added to the original file name.
+
+#### Directory Mode
+```sh
+main.exe --directory path_to_your_directory
 ```
 
+The program will iterate over all images in the directory, and for each image, it will create two new images in the "left" and "right" directories with the suffixes _left and _right added to the original file name.
+
+### As a Python Script
+You can run the script with either the path to a single image you want to split or a directory containing multiple images.
+
+To split a single image:
+
+```sh
+python main.py --image_path path_to_your_image.jpg
+```
 The script will create two new images in the "left" and "right" directories with the suffixes _left and _right added to the original file name.
 
+To split all images in a directory:
+
+```sh
+python main.py --directory path_to_your_directory
+```
+
+The script will iterate over all images in the directory, and for each image, it will create two new images in the "left" and "right" directories with the suffixes _left and _right added to the original file name.
+
+## Build from Source
