+If a module listed in @code{initrd-modules} is not included in the
+Linux-libre kernel, then the location to it must be added to the
+@code{kernel-loadable-modules} list.
+
+For example, if you need the driver for a Realtek RTL8821CE wireless
+network adapter for mounting the root filesystem over NFS, your
+configuration might include the following:
+
+@lisp
+(operating-system
+  ;; @dots{}
+  (initrd-modules (cons "8821ce" %base-initrd-modules))
+  (kernel-loadable-modules (list (list rtl8821ce-linux-module "module"))))
+@end lisp

 @defvr {Scheme Variable} %base-initrd-modules
 This is the list of kernel modules included in the initrd by default.
