The command line program called `fastapi` is **FastAPI CLI**.

FastAPI CLI takes the path to your Python program (e.g. `main.py`) and automatically detects the `FastAPI` instance (commonly named `app`), determines the correct import process, and then serves it.

For production you would use `fastapi run` instead. 🚀

/// tip

If you want something quick to copy and paste, don't use this example, use the last one below.

Then, when you create an instance of that `Settings` class (in this case, in the `settings` object), Pydantic will read the environment variables in a case-insensitive way, so, an upper-case variable `APP_NAME` will still be read for the attribute `app_name`.
