 * Detail usage
 
+** Applicability
+
+You can control when vlf-mode is invoked or offered as choice with the
+*vlf-application* customization option.  By default it will offer VLF
+when opening large files.  There are also options to never use it (you
+can still call *vlf* command explicitly); to use it without asking for
+large files or to invoke it on all files.  Here's example setup such
+that vlf-mode automatically launches for large files:
+
+#+BEGIN_EXAMPLE
+(custom-set-variables
+ '(vlf-application 'dont-ask))
+#+END_EXAMPLE
+
+** Keymap
+
+All VLF operations are grouped under the *C-c C-v* prefix by default.
+Here's example how to add another prefix (*C-x v*):
+
+#+BEGIN_EXAMPLE
+(eval-after-load "vlf"
+  '(define-key vlf-prefix-map "\C-xv" vlf-mode-map))
+#+END_EXAMPLE
