+This ARM Ltd. Versatile target is intended to be used with the Qemu emulator.
+It can be used to prototype an OpenWrt firmware targetting ARM-based hardware.
+One could also use it to troubleshoot ARM applications without access to real
+hardware.
+
+To use the images built by OpenWrt with qemu, use the following commands:
+
+qemu-system-arm -M versatilepb -kernel bin/versatile/openwrt-versatile-vmlinux.elf -nographic -m 128
+
+and enjoy the system booting.
