 ### Setup MQTT:
 Modify config.json:
   Change the IP, username, and password to match the user you have made for Home Assistant (or you can make a separate user for this script)
+
+### Configure the script to run on startup (DEBIAN/LINUX ONLY)
+1. Install tmux
+2. Create a script that starts the tmux session and runs python:
+/home/user/startup.sh:
+```
+#!/bin/bash
+
+# Start a new tmux session named 'emails'
+tmux new-session -d -s emails
+
+# Send commands to the 'emails' session
+tmux send-keys -t emails 'cd /opt/Frigate-SMTP' C-m
+tmux send-keys -t emails 'python3 main.py' C-m
+```
+
+sudo chmod +x /home/user/startup.sh
+
+3. Create a systemctl service:
+
+/etc/systemd/system/frigate-smtp.service:
+```
+[Unit]
+Description=Frigate SMTP Service
+After=network.target
+
+[Service]
+Type=forking
+ExecStart=/opt/Frigate-SMTP/startup.sh
+WorkingDirectory=/opt/Frigate-SMTP
+Restart=on-failure
+User=root
+
+[Install]
+WantedBy=multi-user.target
+```
+
+`sudo systemctl daemon-reload
+sudo systemctl enable frigate-smtp.service
+sudo systemctl start frigate-smtp.service`
+
+4. Verify it works:
+`sudo systemctl status frigate-smtp.service`
+OR
+`tmux attach -t emails` (remember to exit safely by pressing CTRL+B then D)
