1: install the OpenSSH package
(click, Install, Confirm, Close, Back)
2: open Wi-Fi from Settings
3: click your network's
4: read the "IP Address" field
5: open Terminal on desktop
(command-space, "Terminal", enter)
Or if you're on Windows, you can use a desktop terminal application such as PuTTY (http://www.putty.org/).
6: run "ssh root@<ip-address>"
(example: ssh firstname.lastname@example.org)
7: wait a few minutes (just once)
(it's generating some crypto keys)
8: accept new computer host key
(if it doesn't ask you, that's fine)
9: log in with password "alpine"
(you should change this now)
