Utilisées par FastAPI / Starlette :

- <a href="https://pythonhosted.org/itsdangerous/" target="_blank"><code>itsdangerous</code></a> - 需要使用 `SessionMiddleware` 支援時安裝。
- <a href="https://pyyaml.org/wiki/PyYAMLDocumentation" target="_blank"><code>pyyaml</code></a> - 用於支援 Starlette 的 `SchemaGenerator` (如果你使用 FastAPI，可能不需要它)。

用於 FastAPI / Starlette：

The `mkdocs.yml` file will have only the following content:

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

The language code would normally be in the <a href="https://en.wikipedia.org/wiki/List_of_ISO_639_language_codes" class="external-link" target="_blank">ISO 639-1 list of language codes</a>.
