 ### Configuration Management
 - All configuration is TOML-based using `config.toml`
-- Default values are provided in `src/config.cpp`
-- Configuration sections: server, commit, subscription
+- Comprehensive documentation available in `config.md`
+- Type-safe parsing with validation and bounds checking
 - Always validate configuration values and provide meaningful errors
