 ### Systemd Relationship Nomad - Docker
 
-The Nomad and Docker systemd services are connected via a systemd `PartOf` relationship.
-In a systemd overwrite (`/etc/systemd/system/nomad.service.d/override.conf`), the `PartOf` relationship is defined (`[Unit]
-PartOf = docker.service`).
+We suggest to connect the Nomad and Docker systemd services through a systemd `PartOf` relationship.
+In a systemd overwrite (`/etc/systemd/system/nomad.service.d/override.conf`), the `PartOf` relationship can be defined as follows:
+
+```ini
+# /etc/systemd/system/nomad.service.d/override.conf
+[Unit]
+PartOf = docker.service
+```
+
 This results in Nomad being restarted once Docker restarts, but not vice versa.
