+            86Box is a hypervisor and IBM PC system emulator that specializes
+            in running old operating systems and software designed for IBM
+            PC systems and compatibles from 1981 through fairly recent
+            system designs based on the PCI bus.
+
+            It supports various models of PCs, graphics and sound
+            cards, and CPUs.
+        </p>
+        <p>
+            To use 86Box you will need to dump BIOS ROMs for each machine you
+            want to emulate.
