Open Stack

Dear list,

i've just made my first openstack experiences with a three node 
testsetup and openstack kilo. The whole environment was virtualized, so 
I had to use nested virtualization.

Now I have 3 real servers and I want to repeat my setup but with an 
actual release of openstack liberty. My servers are running CentOS 7. 
But the installation docs for openstack liberty and centos are not yet 
available.

Is it save to use the old docs for kilo or should I wait for the release 
of the liberty docs?

Regards,

Joerg
