SUSE Manager/Uyuni - any experts in the house?

[8bit]

This may be a bit of a long shot but I don't suppose we have any Linux folks with experience of any of the above in the house? I'm setting up SUSE Manager for a POC and struggling a bit with the first steps. I've managed to bootstrap a SLES machine to it but having a hard time with CentOS. The documentation is pretty hopeless and I'm not finding a lot about it online. There is a bit more on Uyuni but still not getting there...
