Guide to installing Volumio on PC HDD

Is there a ELI5 guide to installing Volumio on the HDD of a PC? I don’t use the PC and literally want it to boot into Volumio as that will be the sole purpose of the PC, so I am happy for the existing Windows installation to be completely wiped.

I’d rather not buy an SD card when I’ve got a perfectly good hard drive not being used for anything else.

Thanks in advance!
