Import config text file to update Cisco Firewall? {RESOLVED}

I've only ever done this once using Telnet via written instructions, and have lost the instructions, but I had to switch out a Cisco Pix 506e and need to import the backup config file and don't remember the telnet commands to do it.

If someone could give me a quick rundown on how to do it via Telnet or the Cisco GUI command line it would be much appreciated. I need to do this tomorrow to get my video conferencing back up. (We used to have an outsourced company manage the pix and I currently only really know how to do some basic monitoring and add VPN users. I understand the Cisco GUI, and I understand Telnet, but don't know the Cisco syntax and commands

I ended up figuring how to update the configuration using the PDM Command Line.
