    By declaring `response_class=HTMLResponse` the docs UI will be able to know that the response will be HTML.

!!! note "Technical Details"
    You could also use `from starlette.templating import Jinja2Templates`.

    **FastAPI** provides the same `starlette.templating` as `fastapi.templating` just as a convenience for you, the developer. But most of the available responses come directly from Starlette. The same with `Request` and `StaticFiles`.
