+This file shall give additional information on how to set up a network
+environment with Ethernet-over-EtherCAT devices.
+
+A virtual network interface will appear for every EoE-capable slave. The
+interface naming scheme is eoeXsY, where X is the master index and Y is the
+slave's ring position. Please provide a network configuration file for any of
+these interfaces. On SUSE systems, these can look like the following:
+
+/etc/sysconfig/network/ifcfg-eoe0s14:
+IPADDRESS=10.0.0.14/8
+STARTMODE=auto
+
+This will tell the ifupd to configure and open the device after it appears.
+
+If the interfaces shall be part of a network bridge, the IPADDRESS line is not
+necessary. Instead, copy the file script/ifup-eoe.sh to your systems if-up.d
+directory (on SUSE, this is /etc/sysconfig/network/if-up.d), and customize the
+included variables.
