So

I had a break from xbmc for a while, now i orderd the new asrock 3d htpc, and i wanted to know how you install other skins like rapier and focus with the live cd.

They are not in the addons folder in the beta.

Some skins are packaged as zip files. There is an option to install an addon from zip.

[AuXBoX]

either install them as a zip file in the addons section or put them in ~/.xbmc/addons/
