+About this project
+------------------
+
+This project provides a Nova virtualization driver for the z/VM hypervisor of
+IBM z Systems and IBM LinuxOne machines.
+
+z/VM provides a highly secure and scalable enterprise cloud infrastructure
+and an environment for efficiently running multiple diverse critical
+applications on IBM z Systems and IBM LinuxONE with support for more
+virtual servers than any other platform in a single footprint.
+These z/VM virtual servers can run Linux, z/OS and more.
+The detailed information can be found at http://www.vm.ibm.com/
+
+The KVM hypervisors on z Systems and LinuxONE machines are supported
+by separate Nova virtualization drivers:
+
+* KVM is supported by the standard libvirt/KVM driver in the
+  `openstack/nova <http://git.openstack.org/cgit/openstack/nova>`_
+  project.
