A minor update. Not happy with the original wording.

 # SmarAct MCS Tango device server.
 
 There are two separate versions of the device server, one for positioners 
-with encoder (sensor) and the other for those without encoder (sensorless).
+with encoder (sensor) and the other for those without encoder (sensorless)
+as their behaviour differs considerably.
 
-An MCS controller can control a number of positioners of both types, one 
-per channel. We have used 3, 6, 9 and 12 channel versions.
-
-Commands are ASCII, device servers send strings and parse replies.
-
-Typical installation consists of a socket-srv device server connected to
-the controller and an instance of Smaract server per positioner.

+Symbolic links to the Python files should be created in the deployment
+directory named respectively smaractmcs-srv and smaractmcs_ne-srv.
