+By default this plugin does not cache responses with ``no-store`` or ``private`` instructions. If you need to cache
+responses with these cache directives you should setup the plugin with ``CachePlugin::clientCache($pool, $streamFactory, $options);``

 It does store responses with cookies or a ``Set-Cookie`` header. Be careful with
 the order of your plugins.
