+Libvirt API for virtualization
+==============================
+
+Libvirt provides a portable, long term stable C API for managing the
+virtualization technologies provided by many operating systems. It
+includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
+vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
+Hypervisor.
+
+For some of these hypervisors, it provides a stateful management
+daemon which runs on the virtualization host allowing access to the
+API both by non-privileged local users and remote users.
+
+Layered packages provide bindings of the libvirt C API into other
+languages including Python, Perl, PHP, Go, Java, OCaml, as well as
+mappings into object systems such as GObject, CIM and SNMP.
+
+Further information about the libvirt project can be found on the
+website:
+
+*  <https://libvirt.org>
+
+
+License
+-------
+
+The libvirt C API is distributed under the terms of GNU Lesser General
+Public License, version 2.1 (or later). Some parts of the code that are
+not part of the C library may have the more restrictive GNU General
+Public License, version 2.1 (or later). See the files COPYING.LESSER
+and COPYING for full license terms & conditions.
+
+
+Installation
+------------
+
+Libvirt uses the GNU Autotools build system, so in general can be built
+and installed with the usual commands. For example, to build in a manner
+that is suitable for installing as root, use:
+
+```
+$ ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
+$ make
+$ sudo make install
+```
+
+While to build & install as an unprivileged user
+
+```
+$ ./configure --prefix=$HOME/usr
+$ make
+$ make install
+```
+
+
+The libvirt code relies on a large number of 3rd party libraries. These will
+be detected during execution of the configure script and a summary printed
+which lists any missing (optional) dependencies.
+
+
+Contributing
+------------
+
+The libvirt project welcomes contributions in many ways. For most components
+the best way to contribute is to send patches to the primary development
+mailing list, using the `git send-email` command. Further guidance on this
+can be found in the `HACKING` file, or the project website
+
