### Brief System Overview

The top-level scripts and utility scripts should be fairly well-documented. Here
is a brief explanation of how they tie together:

1.  `envs/*` are lists of variables made with bash syntax. A user must set a
    `TFCI` env param pointing to a list of `env` files.

    <exportedArtifact>org.apache.maven:maven-plugin-api</exportedArtifact>
    <exportedArtifact>org.apache.maven:maven-plugin-descriptor</exportedArtifact>
    <exportedArtifact>org.apache.maven:maven-plugin-parameter-documenter</exportedArtifact>
    <exportedArtifact>org.apache.maven:maven-plugin-registry</exportedArtifact>
    <exportedArtifact>org.apache.maven:maven-profile</exportedArtifact>

```Python
q: Union[str, None] = Query(default=None, max_length=50)
```

Cela va valider les données, montrer une erreur claire si ces dernières ne sont pas valides, et documenter le paramètre dans le schéma `OpenAPI` de cette *path operation*.

## Rajouter plus de validation

Vous pouvez aussi rajouter un second paramètre `min_length` :

/// note | Nota

Não importa o que você digite no formulário, ainda não vai funcionar. Mas nós vamos chegar lá.

///

Claro que este não é o frontend para os usuários finais, mas é uma ótima ferramenta automática para documentar interativamente toda a sua API.

Pode ser usada pelo time de frontend (que pode ser você mesmo).

Pode ser usada por aplicações e sistemas de terceiros.

/// note | Nota

No importa lo que escribas en el formulario, aún no funcionará. Pero llegaremos allí.

Esto por supuesto no es el frontend para los usuarios finales, pero es una gran herramienta automática para documentar interactivamente toda tu API.

Puede ser utilizada por el equipo de frontend (que también puedes ser tú mismo).

Puede ser utilizada por aplicaciones y sistemas de terceros.

Então, vá para a interface `/docs`, você verá que o **FastAPI** está usando esses **modelos** para **documentar** a API, e ele também os usará para **serializar** e **validar** os dados.
