Connecting to Wi-Fi

At first boot the device will create an open Wi-Fi network called UNI-GTW. Connect to that network with your phone or computer (if your phone tells you the network has no internet then tap "Connect Anyway" or similar) and navigate to http://192.168.4.1.

There you should be greeted with a dialog asking you for your home Wi-Fi credentials. Select your network and enter your password. After successful connection the device will be accessible on your local network. You can use your router's admin page to determine it's IP address or use a mDNS browser (on Linux you can use avahi-browse -a command).
