+## Retry Options
+
+The following options can be provided when initializing the Gateway to customize the retry behavior of the SDK.
+
+These options are:
+ - max_retries (integer, default 3)
+ - retry_backoff_factor (float, default 1.0)
+ - retry_backoff_jitter (float, default 3.0) 
+
+Those options correspond to their counterparts in [urllib3](https://urllib3.readthedocs.io/en/stable/reference/urllib3.util.html#urllib3.util.Retry)
+
+Example:
+```python
+gw = Gateway(max_retries=5, retry_backoff_factor=0.5, retry_backoff_jitter=1.0)
+````
