+## GUI Usage
+
+A GUI has been developed for easy configuration and plotting of key parameters.  
+
+The Python GUI program is located at pytec/tecQT.py
+
+The GUI is developed based on the Python library pyqtgraph. The environment needed to run the GUI is configured automatically by running:
+
+```shell
+nix develop
+```
+
+The GUI program assumes the default IP and port of 192.168.1.26 23 is used. If a different IP or port is used, the IP and port setting should be changed in the GUI code. 
+
+## Command Line Usage

 - Connect TEC module device 1 to TEC1- and TEC1+.
 - The GND pin is for shielding not for sinking TEC module currents.

-When using a TEC module with the Thermostat, the Thermostat expects the thermal load (where the thermistor is located) to heat up with a positive software current set point, and cool down with a negative current set point.
+When using a TEC module with the Thermostat, the Thermostat expects the thermal load (where the thermistor is located) to cool down with a positive software current set point, and heat up with a negative current set point.

 Testing heat flow direction with a low set current is recommended before installation of the TEC module.
