+## Configuration management
+
+The configuration management package allows you to manage the configuration keys defined in the OCPP 1.6 specification.
+It will automatically check for the validity of the keys and values, and it allows you to register custom key
+validators. It will also trigger callbacks when a key is updated, so you can perform custom logic when a key is changed.
+
+Explore more in the [configuration management ](../ocpp1.6/config_manager) package.
