<b><u>Networking</u></b>

All detected interfaces should show up in the list, but you also have the option \
to type in your own interface. Once you select an interface, select DHCP or \
Static Configuration.  Then once you have set your network settings make sure to \
click Save to add the interface to the list.

Wireless support currently is unavailable, but coming soon!  We even have the \
boxes for it all ready to go.

Don't forget to set a hostname and domain name in the \
"Hostname / Proxy Information / Other" tab!
