The documentation had a broken link to the buildservice
tests for suse. Since we changed this into leap and tumbleweed
the subproject link to :suse became invalid. In addition to
the fix the macro setup and build instructions were moved
to use the kiwi integration tests as example appliance
descriptions. The user experience in building the integration
test images should be better because we only release kiwi
if those appliances build successfully. This Fixes#1812
