again before it's done.'

  `Once upon a time there were three little sisters,' the
Dormouse began in a great hurry; `and their names were Elsie,

Mit `app.include_router()` können wir jeden `APIRouter` zur Hauptanwendung `FastAPI` hinzufügen.

Es wird alle Routen von diesem Router als Teil von dieser inkludieren.

/// note | Technische Details

Tatsächlich wird intern eine *Pfadoperation* für jede *Pfadoperation* erstellt, die im `APIRouter` deklariert wurde.

Hinter den Kulissen wird es also tatsächlich so funktionieren, als ob alles dieselbe einzige Anwendung wäre.

### What is a Program { #what-is-a-program }

The word **program** is commonly used to describe many things:
