+To use vundo, type M-x vundo RET in the buffer you want to undo.
+A undo tree buffer should pop up. To move around, type:
+
+  f   to go forward
+  b   to go backward
+  n   to go to the node below when you at a branching point
+  p   to go to the node above
+  q   to quit, you can also type C-g
+
+By default, you need to press RET to “commit” your change and if
+you quit with q or C-g, the change made by vundo are rolled back.
+You can set ‘vundo-roll-back-on-quit’ to nil to disable rolling
+back.
+
+If you bring up the vundo buffer and make some modification in the
+original buffer, the tree in the vundo buffer doesn’t automatically
+update. Vundo catches up the next time you invoke any command:
+instead of performing that command, it updates the tree.
