+Docker requires a bit of setup before usage. 
+
+You will need to create a ZFS dataset on /usr/docker
+
+# zfs create -o mountpoint=/usr/docker <zroot>/docker 
+
+And lastly enable the docker daemon
+# sysrc -f /etc/rc.conf docker_enable="YES"
+# service docker start
+
+(WARNING)
+
+Starting the docker service will also add the following PF rule:
+
+nat on ${iface} from 172.17.0.0/16 to any -> (${iface})
+
+Where $iface is the default NIC on the system, or the value
+of $docker_nat_iface. This is for network connectivity to docker
+containers in this early port. This should not be needed in future
+versions of docker.
