1947 Please make sure NOW that you have created a user and group 'gnunet'

1950 adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1952 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1953 'gnunet'. Then, you can compile GNUnet with
1956 After that, run (if necessary as 'root')
1958 to install everything.
1960 Each GNUnet user should be added to the 'gnunet' group (may
1961 require fresh login to come into effect):
1962 adduser USERNAME gnunet
1963 (run the above command as root once for each of your users, replacing
1964 "USERNAME" with the respective login names). If you have a global IP
1965 address, no further configuration is required.
1967 For more detailed setup instructions, see https://gnunet.org/installation
1969 Optionally, download and compile gnunet-gtk to get a GUI for
1970 file-sharing and configuration. This is particularly recommended
1971 if your network setup is non-trivial, as gnunet-setup can be
1972 used to test in the GUI if your network configuration is working.
1973 gnunet-setup should be run as the "gnunet" user under X. As it
1974 does very little with the network, running it as "root" is likely
1975 also harmless. You can also run it as a normal user, but then
1976 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
1977 home directory in the end.
1979 Once you have configured your peer, run (as the 'gnunet' user)
1981 to start the peer. You can then run the various GNUnet-tools as
1982 your "normal" user (who should only be in the group 'gnunet').
