+    By default, only i686-pc-mingw32 is built, but you can

+    </p>
+    <pre>make MXE_TARGETS='x86_64-w64-mingw32 i686-w64-mingw32'</pre>
+    <p>
+    or by adjusting the <code>MXE_TARGETS</code> variable
+    in <code>settings.mk</code>.
+    </p>
+    <p>
     You'll always end up with a consistent cross compiling environment.
