 The `timeout` option is used to set the request timeout. You can pass a float, `None` or `httpx.Timeout` to this field. By default, the requests will never timeout. See [Timeout](https://www.python-httpx.org/advanced/timeouts/) for more information.
 
+### `cache_strategy`
+
+The `cache_strategy` option defines how to cache the tokens or http responses. You can provide a githubkit built-in cache strategy or a custom one that implements the `BaseCacheStrategy` interface. By default, githubkit uses the `MemCacheStrategy` to cache the data in memory.

 ### `http_cache`
 
 The `http_cache` option enables the http caching feature powered by [Hishel](https://hishel.com/) for HTTPX. GitHub API limits the number of requests that you can make within a specific amount of time. This feature is useful to reduce the number of requests to GitHub API and avoid hitting the rate limit.
