 ### Options
 
 The following parameters are currently supported from the CLI:
-* `extra_field` - adds an extra schema invalidating field to pointset events
+* `extraPoint=<name>` - adds an extra point with the given name to the device
+  which does not exist in device's metadata with a random value (will trigger
+  validation additional point error)
+* `extraField=<name>` - adds an extra schema invalidating field to pointset events
   (will trigger validation schema error)
-* `extra_point` - adds an extra point to the device which does not exist in
-  device's metadata (will trigger validation additional point error)
-
-Values can be assigned to the parameters e.g. 
-`bin/pubber SITE_PATH PROJECT_ID DEVICE_ID SERIAL_NO extra_point=name_of_point`
+* `no_hardware` - omits the `system.hardware` field from state messages (will
+  trigger validation error, missing required field)
 
 More advanced options can be set by by calling pubber directly with the path a
 configuration file: `pubber/bin/run path/to/config.json`
