+ * @Short_description: A widget used to guide users through multi-step operations
+ * @Title: GtkAssistant
+ *
+ * A #GtkAssistant is a widget used to represent a generally complex
+ * operation splitted in several steps, guiding the user through its pages
+ * and controlling the page flow to collect the necessary data.
+ *
+ * The design of GtkAssistant is that it controls what buttons to show and
+ * to make sensitive, based on what it knows about the page sequence and
+ * the <link linkend="GtkAssistantPageType">type</link> of each page, in
+ * addition to state information like the page
+ * <link linkend="gtk-assistant-set-page-complete">completion</link> and
+ * <link linkend="gtk-assistant-commit">committed</link> status.
+ *
+ * <refsect2 id="GtkAssistant-BUILDER-UI">
+ * <title>GtkAssistant as GtkBuildable</title>
+ * <para>
+ * The GtkAssistant implementation of the GtkBuildable interface exposes the
+ * @action_area as internal children with the name "action_area".
+ *
+ * To add pages to an assistant in GtkBuilder, simply add it as a
+ * <child> to the GtkAssistant object, and set its child properties
+ * as necessary.
