+INSTALLATION
+============
+
+The VMOD is built against a Varnish installation, and the autotools
+use ``pkg-config(1)`` to locate the necessary header files and other
+resources for both Varnish and RE2. This sequence will install the VMOD::
+
+  > ./autogen.sh	# for builds from the git repo
+  > ./configure
+  > make
+  > make check		# to run unit tests in src/tests/*.vtc
+  > make distcheck	# run check and prepare a distribution tarball
+  > sudo make install
+
+See `CONTRIBUTING.rst <CONTRIBUTING.rst>`_ for notes about building
+from source.
+
+If you have installed Varnish and/or RE2 in non-standard directories,
+call ``autogen.sh`` and ``configure`` with the ``PKG_CONFIG_PATH``
+environment variable set to include the paths where the ``.pc`` files
+can be located for ``varnishapi`` and ``re2``. For example, when
+varnishd configure was called with ``--prefix=$PREFIX``, use::
+
+  > PKG_CONFIG_PATH=${PREFIX}/lib/pkgconfig
+  > export PKG_CONFIG_PATH
+
+By default, the vmod ``configure`` script installs the vmod in
+the same directory as Varnish, determined via ``pkg-config(1)``. The
+vmod installation directory can be overridden by passing the
+``VMOD_DIR`` variable to ``configure``.
+
+Other files such as this man-page are installed in the locations
+determined by ``configure``, which inherits its default ``--prefix``
+setting from Varnish.
