+To visualize Mindboggle output with roygbiv, start the Docker image with::
+
+    docker run --rm -ti -v $HOST:$DOCK -p 5000:5000 --entrypoint /bin/bash nipy/mindboggle
+
+and then inside the image, run roygbiv on an output directory::
+
+    roygbiv $OUT/$ID
+
+and open a browser to `localhost:5000`.
+
+Right now, roygbiv only shows summarized data, but Anisha Keshavan is working
+on by-vertex visualizations (for the latter, try `Paraview <https://www.paraview.org/2>`_).
