I apologize for sounding very basic, but how do I use a git on a UNA installation? I am a user, not a developer and I am currently changing the layout via mysite.c*m/studio and it is changing live as I go. When the public start using this, how do I minimize the risk to them? Are you saying I should install my Una on Github, and then push the files to my server? I have no idea which files change when I use the Studio. (I never really  used Github, not being a developer). Until now I have used Wordpress with a Version Control plugin. Una is much more powerful, but I can also see us breaking things when we try to change the layout because it is a heavy learning curve and a "try it and see" approach. 

If you think my best approach is to just continually backups on cPanel, that is OK. I just need to know before I put this into a "real life" environment, as I know we'll break things occasionally! :)
