+<H1>OpenVG State Tracker</H1>
+
+<p>
+The current version of the OpenVG state tracker implements OpenVG 1.0.
+</p>
+<p>
+More informations about OpenVG can be found at <a href="http://www.khronos.org/openvg/">http://www.khronos.org/openvg/</a> .
+</p>
+<p>
+The OpenVG state tracker depends on the Gallium architecture and a working EGL implementation.
+</p>
+
+
+<h2>Building the library</h2>
+<ol>
+<li>Build Mesa3D with Gallium3D. Any build that builds Gallium3D libraries and EGL will suffice</li>
+<li>cd src/gallium/state_trackers/vega; make</li>
+<li>The last step will build libOpenVG library. You can add the libdir to LD_LIBRARY_PATH or install libOpenVG</li>
+</ol>
+
+<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"
+</pre>
+
+<h2>Notes</h2>
+<ul>
+<li>EGL_DRIVER environmental variable: forces usage of a specific EGL driver. Unless you force egl_softpipe the implementation will look for a DRI hardware accelerate driver and unless you have a Gallium driver that supports it, you'll see crashes</li>
+</ul>
