[arch-general] ikev2 strongswan client on Arch

Hi I have successfully setup strongswan VPN server following instructions here[1]. I tested the server by connecting a Blackberry client and a Windows Phone client. Both used IKEv2 and worked fine. I have another laptop, running Arch, that I want to connect to the VPN server. But I can't figure how to configure strongswan as client. The link [1] doesn't describe it. Neither could I find such information from google. Regards, [1] https://wiki.archlinux.org/index.php/StrongSwan
