-In order to establish a uniform convention, comment lines should always start with a hash character (`#`).
+If `arg` is an integer value, then `value` is the name of the collision domain to which interface eth`arg` of device `device` must be connected. The syntax is as follows:
+
+- `arg`: An integer value representing the interface number (e.g., 0).
+- `CD1`: The name of the collision domain to which the specified interface must be connected. Note that the name of the collision domain must not contain spaces (" "), commas (",") and dots (".").
+- `/MAC_ADDR`: An optional parameter to specify the MAC address of the interface of `device` (MAC address must be in the format `XX:XX:XX:XX:XX:XX`). If `MAC_ADDR` is not provided, Kathara will assign a random one.
+
+### EXAMPLES
+
+1. Connect eth0 of `pc1` to collision domain `CD1` with a random MAC address:
+	```
+	pc1[0]="CD1"
+	```
+
+2. Connect eth1 of `pc1` to collision domain `CD2` with the specified MAC address:
