 Data collection and visualization
 ---------------------------------
 
-The easiest way to manage data collection and visualization is to have
-a terminal window with 3 tabs.  One tab is used for ``bsui``, the data
-acquisition program.  A second tab is for the Kafka consumer which
-handles most data visualization chores.  The third tab is just a
-normal bash command line, which is always handy to have available.
+Data collection and visualization are separate things and should be
+managed separately.

+On the main virtual desktop, open a terminal window for bsui.  At the
 command line type ``bsui``.  ``bsui`` startup at BMM is rather
 time-consuming, but after a couple minutes it is ready to go.
 
 
-Now go to the tab for the Kafka consumer.  At the command line, type
-``run-consumer``.  This will take a minute or so to start, eventually
-saying ``Ready to receive documents...``.  At this point, scans will
-generate plots.
+On the right-most virtual desktop, you will setup the Kafka file and
+plot workers as explained in :numref:`the section on Kafka workers
