Whonix + Tails ??

I often see people talking about “Whonix + Tails”
I don’t find any infos on how to combine these two though… Could anybody help me on this one please?

There is a project called HiddenVM on Github which implements this. It installs Whonix to a veracrypt hidden volume on Tails. Do a DuckDuckGo search you will find it.
