-osmo-smdpp currently doesn't have any configuration file or command line options.  You just run it,
-and it will bind its plain-HTTP ES9+ interface to local TCP port 8000.

+osmo-smdpp currently doesn't have any configuration file.
 
+There are command line options for binding:
+
+Bind the HTTP ES9+ to a port other than 8000::
+
+  ./osmo-smdpp.py -p 8001
+
+Bind the HTTP ES9+ to a different local interface::
+
+  ./osmo-smdpp.py -H 127.0.0.1
