 </ol>
 
 <h3>Sample build</h3>
 A sample build looks as follows:
 <pre>
-  $ ./configure --with-state-trackers=egl,vega --enable-gallium-intel
+  $ ./configure --disable-opengl --enable-openvg
   $ make
   $ make install
 </pre>
 
-<h2>OpenVG Demos</h2>
+<p>It will install <code>libOpenVG.so</code>, <code>libEGL.so</code>, and one
+or more EGL drivers.</p>
 
-<p>
-To build the OpenVG demos:
-</p>
-<pre>
-  cd progs/openvg
-  make
-</pre>
-<p>
-To run a demo:
-</p>
-<pre>
-  cd openvg/demos
-  ./lion
