+      This sample demonstrates the PolylineLinkingTool, which replaces the standard LinkingTool. The tool is defined in its own
+      file, as <a href="PolylineLinkingTool.ts">PolylineLinkingTool.ts</a>.
+    </p>
+    <p>
+      The user starts drawing a new link from a node in the normal manner, by dragging from a port, which for feedback purposes
+      has a "pointer" cursor. Normally the user would have to release the mouse near the target port/node. However with the
+      PolylineLinkingTool the user may click at various points to cause the new link to be routed along those points. Clicking
+      on the target port completes the new link. Press <b>Escape</b> to cancel, or <b>Z</b> to remove the last point.
+    </p>
+    <p>
+      Furthermore, because <a>Link.resegmentable</a> is true, the user can easily add or remove segments from the route of
+      a selected link. To insert a segment, the user can start dragging the small diamond resegmenting handle. To remove
+      a segment, the user needs to move a regular reshaping handle to cause the adjacent two segments to be in a straight
+      line.
+    </p>
+    <p>
+      The PolylineLinkingTool also works with orthogonally routed links. To demonstrate this, uncomment the two lines that initialize
+      <a>Link.routing</a> to be <a>Link.Orthogonal</a>.
