+## Static files
+
+As well as the `FileResponse` class, Starlette also includes ASGI applications
+for serving a specific file or directory:
+
+* `StaticFile(path)` - Serve a single file, given by `path`.
+* `StaticFiles(directory)` - Serve any files in the given directory.
+
+You can combine these ASGI applications with Starlette's routing to provide
+comprehensive static file serving.
+
+```python
+from starlette.routing import Router, Path, PathPrefix
+from starlette.staticfiles import StaticFile, StaticFiles
+
+
+app = Router(routes=[
+    Path('/', app=StaticFile('index.html')),
+    PathPrefix('/static/', app=StaticFiles(directory='static')),
+])
