 ## Development
 
 From the root directory, run `pip install -r requirements.txt` to install the package (and all dependencies) in editable mode.  
-Use `flask --app flaskr run` to run app. The package will be updated as you edit files.
+Use `gunicorn -w 2 'flaskr:create_app()'` to run app. Increase the number of workers using the `-w` argument if desired. The package will be updated as you edit files.
 
 ## Production
 Run `python -m build --wheel` to generate the wheel, and install the wheel (found in `dist/`) in the production environment.  
-Use `flask --app flaskr run` to run app. To update package, you will need to install a new wheel.
+Use `gunicorn -w 2 'flaskr:create_app()'` to run app. Increase the number of workers using the `-w` argument if desired. To update package, you will need to install a new wheel.
 
 ## Initializing database
 The first time you install the app in each environment, you need to initialize database using `flask --app flaskr init-db`. This only needs to be run once per environment, and **will delete existing database if run again**.
