Open Stack

Hi Mark,

I followed this guide to do a "git clone" specifying the branch "-b" to
"stable/wallaby" [1]. What additional steps do I need to do to get the
latest commits?

[1] OpenStack Docs: Overcloud
<https://docs.openstack.org/kayobe/wallaby/configuration/scenarios/all-in-one/overcloud.html>

Kind regards,

Tony Pearce
