 <h2>Changes to build system:</h2>
 <ul>
+<li><b>Tests are no longer built by default in ns-3</b>
+<p>
+You can now make tests be built in ns-3 in two ways.
+<ol>
+<li> Using build.py when ns-3 is built for the first time:
+<pre>
+    ./build.py --enable-tests
+</pre>
+<li> Using waf once ns-3 has been built:
+<pre>
+    ./waf configure --enable-tests
+</pre>
+</ol>
+</p></li>
 </ul>
