Include Jade chunk from a parent directory

I would like to make a Jade file include.jade available as an include to other Jade files file.jade, layout.jade in this directory structure:

layouts/layout.jade
documents/file.jade
includes/include.jade

The following are not working:

include ../includes/include.jade
include /includes/include.jade
include "../includes/include.jade"

Is there a way to specify the parent folder in the Jade include directive?
Or is there another way to achieve inclusion in files within different directories?

You don't need the .jade extension. Try:

include ../includes/include
