LUKS install

I want to replace my current Antergos installation.
In order to do that, I need a full LUKS (without LVM) system setup, as I have it in my current install.

I found some guide in Gentoo forum, but is there any existing guide to do so easily?
Usually (on the arch or debian side) one can do that at install. I did not find the options.

Many thanks

Hi Nadir,
The CL has a ready-made encryption solution for user directories. The entire system is not encrypted. We chose this solution to protect the data without noticeable performance losses.

I really think this is a good solution.
btw I need improved one because of my activity and I am ready to buy high end hw. So I’ll try by hand to recrypt root after install, I think the hard part will be the grub config,
