Se você precisar fazer isso, edite o `mkdocs.yml` para sua nova linguagem, teremos algo como:

```YAML hl_lines="5"
site_name: FastAPI
# Mais coisas
theme:
  # Mais coisas
  language: xx
```

Altere essa linguagem de `xx` (do seu código de linguagem) para `en`.

Então você poderá iniciar novamente o _servidor ao vivo_.

これは、テーマがその言語をサポートしていないことを意味します (この場合は、`xx`の2文字の偽のコード) 。

ただし、心配しないでください。テーマ言語を英語に設定して、ドキュメントの内容を翻訳できます。

その必要がある場合は、新しい言語の`mkdocs.yml`を次のように編集してください:

```YAML hl_lines="5"
site_name: FastAPI
# More stuff
theme:
  # More stuff
  language: xx
```

その言語を`xx` (あなたの言語コード) から`en`に変更します。

その後、ライブサーバーを再起動します。

#### 結果のプレビュー

`./scripts/docs.py`のスクリプトを`live`コマンドで使用すると、現在の言語で利用可能なファイルと翻訳のみが表示されます。
