+It's important for your witness to start when your system boots up. The filepaths here assume that you installed your witness into `/home/ubuntu/peerplays`
+
+Create a logfile to hold your stdout/err logging
+```bash
+sudo touch /var/log/peerplays.log
+```
+
+Save this file in your peerplays directory. `vi /home/ubuntu/peerplays/start.sh`
+```bash
+#!/bin/bash
+
+cd /home/ubuntu/peerplays
+./programs/witness_node/witness_node &> /var/log/peerplays.log
+```
+Make it executable
+```bash
+chmod 744 /home/ubuntu/peerplays/start.sh
+```
+Create this file: `sudo vi /etc/systemd/system/peerplays.service`
+Note the path for start.sh. Change it to match where your start.sh file is if necessary.
