- This chapter describes how to declare customizable variables and
-customization groups for classifying them. We use the term

-customization groups, as well as faces.
-
- @xref{Defining Faces}, for the @code{defface} macro, which is used
-for declaring customizable faces.
+ Users of Emacs can customize variables and faces without writing
+Lisp code, by using the Customize interface. @xref{Easy
+Customization,,, emacs, The GNU Emacs Manual}. This chapter describes
+how to define @dfn{customization items} that users can interact with
+through the Customize interface.
+
+ Customization items include customizable variables, which are
+defined with the
+@ifinfo
+@code{defcustom} macro (@pxref{Variable Definitions});
+@end ifinfo
+@ifnotinfo
+@code{defcustom} macro;
+@end ifnotinfo
+customizable faces, which are defined with @code{defface} (described
+separately in @ref{Defining Faces}); and @dfn{customization groups},
+defined with
+@ifinfo
+@code{defgroup} (@pxref{Group Definitions}),
+@end ifinfo
+@ifnotinfo
+@code{defgroup},
