Dadurch werden alle diese unabhängigen MkDocs-Sites für jede Sprache erstellt, kombiniert und das endgültige Resultat unter `./site/` gespeichert.

Dieses können Sie dann mit dem Befehl `serve` bereitstellen:

<div class="termy">

```console
// Verwenden Sie das Kommando „serve“ nachdem Sie „build-all“ ausgeführt haben.

```

In this example, the function `generate_html_response()` already generates and returns a `Response` instead of returning the HTML in a `str`.

By returning the result of calling `generate_html_response()`, you are already returning a `Response` that will override the default **FastAPI** behavior.
