+});
+```
+
+This allows you to enter vimception by going clicking on <code>Help ->
+vimception </code>. To leave vimception, save and reload the notebook. If you
+uncomment the last line to *always* start vimception, there will not be a way to
+get out of vimception mode without editing custom.js and then reload the page.

 It's all very rough right now, I'm working on it, so hang tight.
