    From the README

    Network packet processor that bypasses Deep Packet Inspection (DPI) using netfilter queue manipulation.

    That's it. The installer will take care of the rest

    If something went wrong try to run it with the flag --sysinfo - this will diagnose the system

    Or pass --help to get more information about the possible options.
