Open „boot“ in the \client folder (or „boot.cfg“ if you have file extensions shown). If you want to play on a local server, download a server like 0.5.1 and extract all of the files before starting „LUNI Server.exe“. If you want to play on a public server, connect to the web interface, for example http://5.230.147.129/ for Jonny’s server, and register an account. Now with the boot file you opened, edit AUTHSERVERIP=0:localhost, if you want to connect to a local server or AUTHSERVERIP=0:(public server's IP), for connecting to a public server (for Jonny’s server, AUTHSERVERIP=0:5.230.147.129). After this is done, all you have to do to play is run „legouniverse.exe“ in the client folder.
