+    *********
+
+    This target produces an image for
+    QEMU, the "generic and open source machine emulator and
+    virtualizer".
+
+    MIPS QEMU emulates a "Malta" board, which was an ATX form factor
+    evaluation board made by MIPS Technologies, but mostly in Liminix
+    we use paravirtualized devices (Virtio) instead of emulating
+    hardware.
+
+    Building an image for QEMU results in a :file:`result/` directory
+    containing ``run.sh`` ``vmlinux``, and ``rootfs`` files. To invoke
+    the emulator, run ``run.sh``.
+
+    The configuration includes two emulated "hardware" ethernet
+    devices and the kernel :code:`mac80211_hwsim` module to
+    provide an emulated wlan device. To read more about how
+    to connect to this network, refer to :ref:`qemu-networking`
+    in the Development manual.
