 A Cross-Domain Virtualizer operating system kernel for x86-64, written entirely in the Dust Programming Language (DPL).
 
+For `xdv-os` bare-metal image boot/runtime, the kernel sector also provides
+`sector/xdv_kernel/src/kernel_runtime_shell.asm`, which implements the runtime

 ## Overview
 
 XDV v0.2 is a multi-domain operating system kernel that supports three computational domains:
