-### DDS Shape Subscriber Operator
+# DDS Shape Subscriber Operator
 
 The DDS Shape Subscriber Operator subscribes to and reads from the `Square`, `Circle`, and
 `Triangle` shape topics as used by the [RTI Shapes Demo](https://www.rti.com/free-trial/shapes-demo).
 It will then translate the received shape data to an internal `Shape` datatype for output
 to downstream operators.
