@dhruva2000 I couldn't take another incomplete article as I've started
so many without finishing them myself. This seemed like an easy one, so
I've started adding some details. Once my local build completes, I'll
add a note of how long it took and add some more details to wrap up
how to boot the new kernel.

See merge request !77
