+This Malta target is intended to be used with the Qemu emulator. It can be used
+to prototype an OpenWrt firmware for MIPS processors. One could also use it to
+troubleshoot MIPS applications without access to real hardware.
+
+To use the images built by OpenWrt with qemu, use the following commands:
+
+For the 32 bit little-endian image:
+qemu-system-mipsel -kernel bin/targets/malta/le/openwrt-malta-le-vmlinux-initramfs.elf -nographic -m 256
+
+For the 32 bit big-endian image:
+qemu-system-mips -kernel bin/targets/malta/be/openwrt-malta-be-vmlinux-initramfs.elf -nographic -m 256
+
+For the 64 bit little-endian image:
+qemu-system-mips64el -kernel bin/targets/malta/le64/openwrt-malta-le64-vmlinux-initramfs.elf -cpu MIPS64R2-generic -nographic -m 256
+
+For the 64 bit big-endian image:
+qemu-system-mips64 -kernel bin/targets/malta/be64/openwrt-malta-be64-vmlinux-initramfs.elf -cpu MIPS64R2-generic -nographic -m 256
+
+and enjoy the system bootin.
