### Es in der Dokumentation ansehen

Jetzt können Sie Ihre Anwendung mit Uvicorn starten und auf <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a> gehen.

Sie werden sehen, dass Ihre Dokumentation die normalen *Pfadoperationen* und jetzt auch einige **Webhooks** enthält:

Wenn Sie eine ältere Version haben, werden Sie Fehler angezeigt bekommen, wenn Sie versuchen, `Annotated` zu verwenden.

Bitte [aktualisieren Sie FastAPI](../../deployment/versions.md#upgrade-der-fastapi-versionen){.internal-link target=_blank} daher mindestens zu Version 0.95.1, bevor Sie `Annotated` verwenden.

## Install custom exception handlers { #install-custom-exception-handlers }

You can add custom exception handlers with <a href="https://www.starlette.io/exceptions/" class="external-link" target="_blank">the same exception utilities from Starlette</a>.

Let's say you have a custom exception `UnicornException` that you (or a library you use) might `raise`.
