- Start the server. The first start downloads the game (about 15 GB), so give it several minutes.
- In 7 Days to Die: Join a Game → Connect to IP, enter your IP and port, plus the password if you set one.
Admin: add your Steam ID to serveradmin.xml (inside the Saves folder) and restart, or type commands in the panel Console, which is connected to the server's telnet console: admin add <steamid> 0, say Hello, kick, ban, settime, shutdown.
The Password on the Startup page protects both the join password and the telnet console, so keep it private.
