installing mdadm.

My goal is to have a system where if either drive fails things will a)
continue to run from a single drive, and b) be able to replace the failed
drive with a new one of the same size and have the system rebuild into a
mirrored array again.

It is not clear to me how I need to begin the installation sequence.

My question: Do I install Debian to a single drive and will installing mdadm
then allow me to add the second disk and setup RAID? Do I need to configure
each drive in some way before installing Debian and then mdadm?

If there is an up-to-date "how to" that describes this please just point me
there. I have not found anything that seems to start at the point where I
just have bare metal.
