+### Customizing system integration
+
+The `smbclient` backend needs to get various information about the system it's running on to function
+such as the paths of various binaries or the system timezone.
+While the default logic for getting this information should work on most systems, it possible to customize this behaviour.
+
+In order to customize the integration you provide a custom implementation of `ITimezoneProvider` and/or `ISystem` and pass them as arguments to the `ServerFactory`.

 ## Testing SMB
 
 Use the following steps to check if the library can connect to your SMB share.
