The key updated docs are:

    * [Type Hints with Metadata Annotations](https://fastapi.tiangolo.com/python-types/#type-hints-with-metadata-annotations).
* Tutorial:

## Verwenden von `Annotated` im Typ für den `q`-Parameter { #use-annotated-in-the-type-for-the-q-parameter }

Erinnern Sie sich, dass ich Ihnen zuvor in [Python-Typen-Intro](../python-types.md#type-hints-with-metadata-annotations){.internal-link target=_blank} gesagt habe, dass `Annotated` verwendet werden kann, um Metadaten zu Ihren Parametern hinzuzufügen?

Jetzt ist es soweit, dies mit FastAPI zu verwenden. 🚀

FastAPI is a modern, fast (high-performance), web framework for building APIs with Python based on standard Python type hints.

The key features are:

* **Fast**: Very high performance, on par with **NodeJS** and **Go** (thanks to Starlette and Pydantic). [One of the fastest Python frameworks available](#performance).
