1956 Please make sure NOW that you have created a user and group 'gnunet'

1959 adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1961 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1962 'gnunet'. Then, you can compile GNUnet with
1965 After that, run (if necessary as 'root')
1967 to install everything.
1969 Each GNUnet user should be added to the 'gnunet' group (may
1970 require fresh login to come into effect):
1971 adduser USERNAME gnunet
1972 (run the above command as root once for each of your users, replacing
1973 "USERNAME" with the respective login names). If you have a global IP
1974 address, no further configuration is required.
1976 For more detailed setup instructions, see https://docs.gnunet.org/
1978 Optionally, download and compile gnunet-gtk to get a GUI for
1979 file-sharing and configuration. This is particularly recommended
1980 if your network setup is non-trivial, as gnunet-setup can be
1981 used to test in the GUI if your network configuration is working.
1982 gnunet-setup should be run as the "gnunet" user under X. As it
1983 does very little with the network, running it as "root" is likely
1984 also harmless. You can also run it as a normal user, but then
1985 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
1986 home directory in the end.
1988 Once you have configured your peer, run (as the 'gnunet' user)
1990 to start the peer. You can then run the various GNUnet-tools as
1991 your "normal" user (who should only be in the group 'gnunet').
