Help me to get KZ mod running on my rented se

Hi there guys, I've rented a server about an year ago, and I was wondering, if anybody could help me to setup the KZ scripts on it. I'm a bit newbie on accessing the FTP, and upload the necessary files to get the MOD running.

So, can somebody tell me whats the best KZ mod, what do I need to do to get the mod running, what files should I upload to FTP, etc.

Thanks in advance.

By the way, it´s a Condition Zero server.
