Could you add an explanation to replicate the dotfiles on a new installation

[vincentbenzo]

Thank you you for your work it is really nice !

I am using it on my desktop and the installation went well however now I want to
replicate this installation on my laptop and when I try to
dofiles clone https://myrepo.com /path/to/metadata

I have the following error :
fatal : working tree /home/myname already exists

I think I could go around this error with some option like --separate-git-dir but I am not sure and from your README I can't understand how to use your wrapper for this case.
Thank you in advance for your help
