Hello all!

So I'm trying to do a custom image build, and when I get to the "git clone git://git.kali.org/cdimage.kali.org" part, I receive this error:
"fatal: remote error: repository not exported: /cdimage.kali.org"
Am I doing something wrong or is that feature maybe not available yet? I really like what I've seen so far otherwise though, great job guys!
