+### Breaking Changes
+
+* replace motion remapping with transparent keypad leader.
+
+The `meow-motion-overwrite-define-key` has been changed to `meow-motion-define-key`. and now it
+works just like other key binding helpers.  Users don't have to bind a key to remapped the
+keybinding. Now the keypad leader is transparent when a key is not bound in motion state.  So that
+users can still access the original command with `SPC <original-key>`.

 By default, MOTION state has no keybindings, except ~SPC~ is used as the leader key. The original command on ~SPC~ can be access via ~SPC SPC~.
 
 Users may want a consistent keybindings for movement globally, for example: k/j to move up/down. Usually, you can bind k/j in MOTION state,
-however the original command on k/j is not accessible. To solve the problem, Meow introduce a simple solution.
-
-For any keybinding you defined with ~meow-motion-overwrite-define-key~, the overwritten command will be bound to the key with ~hyper~ modifier.
+however then the original command on k/j is not accessible. To access the original command on k/j, use ~SPC k/j~.
 
 Here's an example: you want use ~j~ as ~next-line~ globally.
 
 #+begin_src emacs-lisp
   (meow-motion-overwrite-define-key '("j" . next-line))
-  (meow-leader-define-key '("j" . "H-j"))
-#+end_src
-
-Now ~j~ will act as ~next-line~, the original command on ~j~ (e.g. ~dired-goto-file~ in ~dired~) will be bound to ~H-j~.
-Since we use ~j~ in the leader for ~H-j~, now we can call it via ~SPC j~.
-
-It is also possible to route the original command(e.g. ~j~) to original motion key(e.g. ~n~).
-
-#+begin_src emacs-lisp
-  (meow-motion-overwrite-define-key '("j" . next-line))
-  (meow-motion-overwrite-define-key '("n" . "H-j"))
 #+end_src
 
-Now you have swapped ~j~ and ~n~.
