The appropriate way to work with Flask-Script is to create a `manage.py` file where you define your Flask application and commands. You can then use the `Manager` class from Flask-Script to add commands and run your application. For example:

```python
from flask import Flask
from flask_script import Manager

app = Flask(__name__)
manager = Manager(app)

@manager.command
def runserver():
app.run()

if __name__ == "__main__":
manager.run()
```

You can run your commands using the terminal with `python manage.py runserver`.
