-tado multi temperature scheduling utility
+tado multi temperature scheduling utility by Ian Atkin, January 2015
 
 At the moment, the tado smart thermometer web and mobile apps only allow a single home temperature to be set.  This is a simple python3 script to allow the home temperature to be changed at defined times.
 
-Having only learned python in the last day I'm sure this code can be massively improved!
+A simple non-authenticated web interface is also included.
 
-Usage:  - copy tadocontrol.py3 and temperatures.db into your directory of choice
-            - edit tadocontrol.py3 to set tado username/password, temperature and time preferences
-            - run tadocontrol.py3 in a terminal to activate
+Having only learned python in the last week I'm sure this code can be massively improved!
 
-Python package dependencies: httplib2, schedule, sqllite3, time
+Usage:  
+- copy tadocontrol.py3, make_table.tpl and temperatures.db into your directory of choice
+- edit tadocontrol.py3 to set tado username/password, network settings for web interface, temperature and time preferences
+- run tadocontrol.py3 in a terminal to activate
+
+Python package dependencies: bottle, httplib2, schedule, sqllite3, time
 
 Tested with python v3.4.0 only
