1945 Please make sure NOW that you have created a user and group 'gnunet'

1948 adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1950 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1951 'gnunet'. Then, you can compile GNUnet with
1954 After that, run (if necessary as 'root')
1956 to install everything.
1958 Each GNUnet user should be added to the 'gnunet' group (may
1959 require fresh login to come into effect):
1960 adduser USERNAME gnunet
1961 (run the above command as root once for each of your users, replacing
1962 "USERNAME" with the respective login names). If you have a global IP
1963 address, no further configuration is required.
1965 For more detailed setup instructions, see https://docs.gnunet.org/
1967 Optionally, download and compile gnunet-gtk to get a GUI for
1968 file-sharing and configuration. This is particularly recommended
1969 if your network setup is non-trivial, as gnunet-setup can be
1970 used to test in the GUI if your network configuration is working.
1971 gnunet-setup should be run as the "gnunet" user under X. As it
1972 does very little with the network, running it as "root" is likely
1973 also harmless. You can also run it as a normal user, but then
1974 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
1975 home directory in the end.
1977 Once you have configured your peer, run (as the 'gnunet' user)
1979 to start the peer. You can then run the various GNUnet-tools as
1980 your "normal" user (who should only be in the group 'gnunet').
