+/**
+ * SECTION:cc-panel
+ * @short_description: An abstract class for Control Center panels
+ *
+ * CcPanel is an abstract class used to implement panels for the shell. A
+ * panel contains a collection of related settings that are displayed within
+ * the shell window.
+ *
+ * # Buildable
+ *
+ * CcPanel implements the GtkBuildable interface, and allows having different
+ * types of children for convenience.
+ *
+ * It is possible to add widgets to the start and end of the panel titlebar
+ * using, respectively, the `titlebar-start` and `titlebar-end` child types.
+ * It is also possible to override the titlebar entirely with a custom titlebar
+ * using the `titlebar` child type.
+ *
+ * Most panels will use the `content` child type, which sets the panel content
+ * beneath the titlebar.
+ *
+ * At last, it is possible to override all custom CcPanel widgets by not setting
+ * any child type.
