 <h3>Sample build</h3>
 A sample build looks as follows:
 <pre>
-make linux-x86-64-debug
-cd src/gallium/state_trackers/vega
-make
-cd ../../../..
-export LD_LIBRARY_PATH=$PWD/lib64
-export EGL_DRIVER="egl_softpipe"
+  make linux-x86-64-debug
+  cd src/gallium/state_trackers/vega
+  make
+  cd ../../../..
+  export LD_LIBRARY_PATH=$PWD/lib64
+  export EGL_DRIVER="egl_softpipe"
 </pre>
 
+<h2>OpenVG Demos</h2>

+<p>
+To build the OpenVG demos:
+</p>
+<pre>
+  cd progs/openvg
+  make
+</pre>
+<p>
+To run a demo:
+</p>
+<pre>
+  cd openvg/demos
+  ./lion
+</pre>
