Hi all,
 
 I need to update an image in the tripleo-puppet-elements repository[0].
 More precisely, I need to update "overcloud-network-midonet".
 
 Before pushing changes upstream I would like to build and test the
 images locally, but I'm having issues finding documentation to do so.
 
 I found a tripleo-incubator doc[1], but I'm not sure this is what I'm
 looking for, or if it is indeed outdated. Or is there another way to
 build the images? Also, the README in [0] does not work.
 
 Can you please point me in the right direction here?
 
 Best regards,
 Alejandro Andreu

There are instructions for building overcloud images in the tripleo
docs[1], and if these are not working the repo for them is here[2].
That said, it is often much easier to use virt-customize[3] on a
existing image to test changes.
