Need the documentation for Gitlab manually setup 7.2.2 under /home/git user in centos 6.5 Final

Hi,

I am running Gitlab 7.2.2 in centos 6.5 under /home/git user. However, I have the backup of all repositories. I need to set up the same Gitlab 7.2.2 using centos 6.5 under /home/git user in another machine. Could you please help me out to provide the documentation and 7.2.2 manual installation archive.

Thanks a lot in advance.
