+## File Uploads
+
+Request parameters that correspond to file uploads can be passed as `bytes`, a [`PathLike`](https://docs.python.org/3/library/os.html#os.PathLike) instance or a tuple of `(filename, contents, media type)`.
+
+```python
+from pathlib import Path
+from cloudflare import Cloudflare
+
+client = Cloudflare()
+
+client.images.v1.create(
+    account_id="023e105f4ecef8ad9ca31a8372d0c353",
+)
+```
+
+The async client uses the exact same interface. If you pass a [`PathLike`](https://docs.python.org/3/library/os.html#os.PathLike) instance, the file contents will be read asynchronously automatically.
+
 ## Handling errors
 
 When the library is unable to connect to the API (for example, due to network connection problems or a timeout), a subclass of `cloudflare.APIConnectionError` is raised.
