+If this is succeeding, you can now proceed to configure Engine API to run as a system daemon using [Systemd](#running-with-systemd) or

 ### Running with Systemd
 
-**tbd**
+The Systemd unit file configuration expects to be running under the user `engineuser`. To create such user type:
+
+```shell
+    sudo adduser engineuser
+    sudo adduser engineuser sudo
+```
+
+Copy the systemd unit file in `./config/sample/systemd` to `/etc/systemd/system`. This configuration file is expecting you to have
+Engine API installed under `/opt/aura/engine-api` and `engineuser` owning the files.
+
+Next login to `engineuser` and give it permissions to the unit file
+
+```shell
+  su engineuser
+  sudo chmod 644 /etc/systemd/system/aura-engine-api.service
+```
+
+Let's start the service
+
+```shell
+sudo systemctl start aura-engine-api
+```
+
+And check if it has started successfully
+
+```shell
+sudo systemctl status aura-engine-api
+```
+
+If you experience issues and need more information, check the syslog while starting the service
+
+```shell
+tail -f /var/log/syslog
+```
+
+You can stop or restart the service with one of these
+
+```shell
+sudo systemctl stop aura-engine-api
+sudo systemctl restart aura-engine-api
+```
+
+Note, any requirements from the [Installation](#installation) step need to be available for that user.
 
 ### Running with Supervisor
 
-Alternatively to Systemd you can start Engine API using [Supervisor](http://supervisord.org/). In `./config/sample/supervisor/aura-engine-api.conf` you can find a example.
