+## Timeouts
+
+HTTPX defaults to including reasonable [timeouts](quickstart.md#timeouts) for all network operations, while Requests has no timeouts by default.
+
+To get the same behavior as Requests, set the `timeout` parameter to `None`:
+
+```python
+httpx.get('https://www.example.com', timeout=None)
+```

 ## Proxy keys
 
 When using `httpx.Client(proxies={...})` to map to a selection of different proxies, we use full URL schemes, such as `proxies={"http://": ..., "https://": ...}`.
