+It is made of two parts: KConfigCore and KConfigGui.
+
+KConfigCore provides access to the configuration files themselves.
+It features:
+
+@itemize
+@item Code generation: describe your configuration in an XML file, and use
+`kconfig_compiler to generate classes that read and write configuration
+entries.
+
+@item Cascading configuration files (global settings overridden by local
+settings).
+
+@item Optional shell expansion support (see docs/options.md).
+
+@item The ability to lock down configuration options (see docs/options.md).
+@end itemize
+
+KConfigGui provides a way to hook widgets to the configuration so that they
+are automatically initialized from the configuration and automatically
+propagate their changes to their respective configuration files.")
