The source project of this merge request has been removed.
Point to the docs from README.Debian
After finding openstack-cluster-installer from "apt-cache search" and installing it, it is absolutely not clear how to use it, and README.Debian does not help in its current state.
Perhaps a better idea might be to install README.md as README.Debian (and merge the PHP SSL warning into it), but that's a bit more involved than what I'm suggesting right now.
