Elle peut être une fonction asynchrone (`async def`) ou une fonction normale (`def`), **FastAPI** saura la gérer correctement.

Dans cet exemple, la fonction de tâche écrira dans un fichier (afin de simuler un envoi d'email).

L'opération d'écriture n'utilisant ni `async` ni `await`, on définit la fonction avec un `def` normal.

Now you can check in your code editor the newly created directory `docs/la/`.

That command created a file `docs/la/mkdocs.yml` with a simple config that inherits everything from the `en` version:

```yaml
INHERIT: ../en/mkdocs.yml
```

You could also simply create that file with those contents manually.
