+## GUI Usage
+
+A GUI has been developed for easy configuration and plotting of key parameters.
+
+The Python GUI program is located at pytec/tec_qt.py.
+
+The GUI is developed based on the Python library pyqtgraph. The GUI can be configured and launched automatically by running:
+
+```
+nix run .#thermostat_gui
+```
+
+## Command Line Usage
