 <p>The method <tt>align</tt> must implement a way to access the matcher implementation. </p>
 
-<p></p>
+<p>The easiest way to do this is to implement the <a href="http://alignapi.gforge.inria.fr/">Alignment API</a> (see details in <a href="http://alignapi.gforge.inria.fr/tutorial/tutorial3/">how to extend the Alignment API with a new matcher</a>). Basically, you need to implement the <tt>AlignmentProcess</tt> interface (method <tt>align</tt>) and extend the <tt>URIAlignment</tt> class (<a href="MyAlignment.java">MyAlignment.java</a>):
