+Contributing a virtualization test
+----------------------------------------------------------------------
+
+virt-what is especially dependent on outside contributors because it's
+hard to even get access to some of the hypervisors out there, and even
+for the common hypervisors there are many different versions and many
+different ways for to break.  For these reasons we are especially
+happy if you contribute to or even just test virt-what :-)
+
+virt-what is a simple shell script.  Add a new hypervisor test to
+'virt-what.in' ('virt-what' in this directory is a generated file).
+
+If you can't contribute a patch, please just send us the following
+data (all as root from inside the guest):
+
+  (1) /proc/cpuinfo
+
+  (2) dmidecode
+
+  (3) If possible, send the output of /usr/libexec/virt-what-cpuid-helper
+
+  (4) Any other /proc and /sys files that may be related to the
+      hypervisor.
+
+  (5) Name of the virtualization system, version, host or guest,
+      and as much other information as possible.
+
+Please send patches, test results or any other data to:
+
+  https://www.redhat.com/mailman/listinfo/virt-tools-list

+Contributing a regression test
+----------------------------------------------------------------------
+
+In the tests/ subdirectory you'll find some existing tests.
+
+These tests are taken from real machines, and we have a policy of
+*only* adding real data here so that our regression tests are
+impeccable.
+
+The virt-what script has a hidden '--test-root' option which allows a
+different root directory to be specified for these regression tests.
+The tests/ subdirectory contains some alternate root filesystems
+(sparsely populated with a few files taken from the real systems) for
+testing.
