The phabricator workflow is not approriate for consumption by those not
inside Bosch or Collabora. The phabricator instance is password protected
and not accessible by the general public. Portions of this workflow also
do not make any sense outside a client relationship.

Move this content to the phabricator wiki where it is more relevant.
