 Next, start the server. You can do this in either debugging mode (where `debug=True`) in Flask or in production mode using Gunicorn.
 
 ```
-python3 app.py --debug (debug mode)
-gunicorn app:app (production mode)
+uv run -- app.py --debug (debug mode)
+uv run -- gunicorn --bind localhost:8080 app:app (production mode)
