 Installation
 ============
 
-Libvirt uses the GNU Autotools build system, so in general can be built
-and installed with the usual commands, however, we mandate to have the
-build directory different than the source directory. For example, to build
-in a manner that is suitable for installing as root, use:
-
-::
-
-  $ mkdir build && cd build
-  $ ../configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
-  $ make
-  $ sudo make install
-
-While to build & install as an unprivileged user
-
-::
-
-  $ mkdir build && cd build
-  $ ../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.
+Instructions on building and installing libvirt can be found on the website:
 
+https://libvirt.org/compiling.html
