Here, it returns a few results, too. I think the most straight-forward is  
this one:

https://wiki.debian.org/SoftwareRAID

For most purposes, I recommend RAID1. If you have four HDDs of identical  
size, RAID10 might be tempting, too, but I'd still consider and possibly  
prefer just creating two independent RAID1 arrays.

If you want to configure it from the installer, these step-by-step  
instructions show all the relevant installer screens:

Also, keep in mind that establishing the mirroring is not all you need to  
do. To really profit from the enhanced reliability, you need to play through  
the recovery scenario, too. I recommend doing this in a VM unless you have  
some dedicated machine with at least two HDDs to play with.
