I don't get it.  That's the whole point of the boot.img, which is made to simply 
dd onto a usb device.  And having booted from that, there is nothing different 
than any other way of booting into the installer except that you have to tell it 
where the install media is.  It is exactly the same as if you had booted the 
install CD or DVD with 'linux askmethod' at the boot prompt to get that 
question.  No special methods or instructions needed, and the only thing that 
won't be obvious until you have done it is that the installer knows how to work 
with the CD iso images saved in a directory.
