説明文は長くて複数行におよぶ傾向があるので、関数<abbr title="ドキュメントに使用される関数内の最初の式（変数に代入されていない）としての複数行の文字列">docstring</abbr>内に*path operation*の説明文を宣言できます。すると、**FastAPI** は説明文を読み込んでくれます。

docstringに<a href="https://en.wikipedia.org/wiki/Markdown" class="external-link" target="_blank">Markdown</a>を記述すれば、正しく解釈されて表示されます。（docstringのインデントを考慮して）
