How to download virtual machines (Kali) and Lab0 video


I’ve been looking for the PTS lab0 series demo video on how to download virtual box for Kali. it would be really helpful to know each of the steps required. Just don’t want to make any mistakes. Has anyone done this step and do you know where the video is? Also, the lab0 video on Linux requirements for PTS. Anyone know where that one is? Cheers.
