Since June 2023, a virtual machine image of z-Tree unleashed is no longer provided.

If you wish to use z-Tree unleashed at this point, you need to follow the instructions for a server setup. To obtain the desktop icons, execute ./ in the scripts directory. You can then proceed to the section entitled "How to run an experiment". This is only sensible if you have a GUI. Otherwise, just use the command line to run your experiments.
