 ```bash
-python main.py --story-concept "An unlikely rebellion of oppressed people fighting against a tyrannical council of wizards"
+python cli.py --story-concept "An unlikely rebellion of oppressed people fighting against a tyrannical council of wizards"
 ```
 
 This will generate a story with a single image and narrative, based on the provided story concept. If you'd like to specify a starting image or limit the story length, include the appropriate parameters:
 
 ```bash
-python main.py --starting-image-path "path/to/image.png" --story-concept "An epic journey through uncharted lands" --story-length 10
+python cli.py --starting-image-path "path/to/image.png" --story-concept "An epic journey through uncharted lands" --story-length 10
+```
+
+If you wish to start the story from a description rather than an image, you can use the `--starting-image-description` parameter like this:
+
+```bash
+python cli.py --starting-image-description "A misty forest at dawn with a mysterious figure in the distance" --story-concept "A lone wanderer discovers an ancient secret in the forest"
 ```
