+# Introduction
 
 The interlock folder contains P1AM-100 code (which is Arduino MKX1000).
 
-## setup using Arduino IDE 1.X
+The Listen2Arduino.py is a script for listening the P1AM-100 output, and put the status, the tritium, Vaccum, and SubPump reading to the fsunuc.physics.fsu.edu database. 
+
+## Setup using Arduino IDE 1.X
 
 The P1AM.h library is needed. 
+
+## Setup system service for the Listen2Arduino.py
+
+copy the listen2P1AM.service to /etc/systemd/system/
+
+run
+
+ sudo systemctl enable listen2P1AM.service
+ sudo systemctl start listen2P1AM.service
+
+## interlock database at fsunuc.physics.fsu.edu
+
+database name : interlock
