    `CMD` takes a list of strings, each of these strings is what you would type in the command line separated by spaces.

    This command will be run from the **current working directory**, the same `/code` directory you set above with `WORKDIR /code`.

# Templates

Sie können jede gewünschte Template-Engine mit **FastAPI** verwenden.

Eine häufige Wahl ist Jinja2, dasselbe, was auch von Flask und anderen Tools verwendet wird.

Es gibt Werkzeuge zur einfachen Konfiguration, die Sie direkt in Ihrer **FastAPI**-Anwendung verwenden können (bereitgestellt von Starlette).

## Abhängigkeiten installieren

Installieren Sie `jinja2`:

<div class="termy">

```console
$ pip install jinja2

/// tip | "Tipp"

Bevorzugen Sie die `Annotated`-Version, falls möglich.
