## Example

    ```python
    from typing import Annotated

    from fastapi import Depends, FastAPI
    from fastapi.security import OAuth2PasswordRequestForm

    app = FastAPI()


    @app.post("/login")
    def login(form_data: Annotated[OAuth2PasswordRequestForm, Depends()]):
        data = {}
        data["scopes"] = []

            return func

        return decorator

    def include_router(
        self,
        router: Annotated[routing.APIRouter, Doc("The `APIRouter` to include.")],
        *,
        prefix: Annotated[str, Doc("An optional path prefix for the router.")] = "",
        tags: Annotated[
            list[str | Enum] | None,
            Doc(
                """

## How It Works { #how-it-works }

The `@app.vibe()` decorator is intended to receive **any HTTP method** (`GET`, `POST`, `PUT`, `DELETE`, `PATCH`, etc.) and **any payload**.

The body should be annotated with `Any`, because the request and the response would be... well... **anything**. 🤷

   *   <li>All non-private static methods are checked such that passing null for any parameter

I would expect `typing_extensions.Doc` to be deprecated and then removed at some point from `typing_extensions`, for that reason there's the new `annotated-doc` micro-package. If you are curious about this, you can read more in the repo for [`annotated-doc`](https://github.com/fastapi/annotated-doc).
