+.SH DEVICES
+Each device has its own directory under /etc/net.
+
+If the device is defined in /etc/net, but it does not exist, it will be created as a bridge.
+.SH ATTRIBUTES
+Each attribute is a plain text file. Each device has 4 optinonal attributes:
+.B ip, mac, gw, master.
+.SH DEFAULT DEVICE
+The default device has its attributes directly stored in /etc/net.
+
+
+If it has a directory under /etc/net, the attributes will be overwritten.
+
+The default device is the first network device listed on your system, in alphabetical order.
+
+For better end-user experience, the device must start with an 'e' or 'w', and must not have a 'u' in its name.
