How do you sync online accounts with the new contacts program in 12.10?

http://askubuntu.com – I am trying to sync my online accounts (google, facebook, anything really) with the new program in Ubuntu 12.10. It gives me the option to change the address book but I can't see how to set up an online account anywhere. Anyone have any ideas? Am I just not looking in the right place? (HowTos)
