## Use `StaticFiles`

* Import `StaticFiles`.
* "Mount" a `StaticFiles()` instance in a specific path.

{* ../../docs_src/static_files/tutorial001.py hl[2,6] *}

/// note | "Technical Details"

You could also use `from starlette.staticfiles import StaticFiles`.

**FastAPI** provides the same `starlette.staticfiles` as `fastapi.staticfiles` just as a convenience for you, the developer. But it actually comes directly from Starlette.

Best practice is to set conventions in a plugin (2). This keeps the underlying object "dumb", so it can be reused in multiple contexts and doesn't contain any special information about how conventions are calculated or what they could be.  In the wild, we've seen some objects set conventions in the object's constructor (3), but this can lead to unexpected assumptions or coupling between plugins.
