-The command `uvicorn main:app` refers to:
+The command `fastapi dev` reads your `main.py` file, detects the **FastAPI** app in it, and starts a server using <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a>.
 
-* `main`: the file `main.py` (the Python "module").
-* `app`: the object created inside of `main.py` with the line `app = FastAPI()`.
-* `--reload`: make the server restart after code changes. Only do this for development.
+By default, `fastapi dev` will start with auto-reload enabled for local development.
