+# Service Configuration
+
+The bulleted list below provides a comprehensive overview of the various configuration settings used in the Hedera Services. These settings are defined in various Config classes,
+each managing a specific aspect of the system. For instance,
+`AccountsConfig.java` controls account-related properties, while
+`ContractsConfig.java` manages smart contract settings.
+This document serves as a valuable resource for understanding how
+Hedera Services can be customized and configured to meet specific requirements.
+For more detailed information on other types of configuration, please refer to the
+[Service Configuration](hedera-node/docs/services-configuration.md).
