1951 Please make sure NOW that you have created a user and group 'gnunet'
1952 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux, type:
1953         addgroup gnunetdns
1954         adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1955
1956 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1957 'gnunet'.  Then, you can compile GNUnet with
1958         make
1959
1960 After that, run (if necessary as 'root')
1961         make install
1962 to install everything.
1963
1964 Each GNUnet user should be added to the 'gnunet' group (may
1965 require fresh login to come into effect):
1966         adduser USERNAME gnunet
1967 (run the above command as root once for each of your users, replacing
1968 "USERNAME" with the respective login names).  If you have a global IP
1969 address, no further configuration is required.
1970
1971 For more detailed setup instructions, see https://gnunet.org/installation
1972
1973 Optionally, download and compile gnunet-gtk to get a GUI for
1974 file-sharing and configuration.  This is particularly recommended
1975 if your network setup is non-trivial, as gnunet-setup can be
1976 used to test in the GUI if your network configuration is working.
1977 gnunet-setup should be run as the "gnunet" user under X.  As it
1978 does very little with the network, running it as "root" is likely
1979 also harmless.  You can also run it as a normal user, but then
1980 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
1981 home directory in the end.
1982
1983 Once you have configured your peer, run (as the 'gnunet' user)
1984         gnunet-arm -s
1985 to start the peer.  You can then run the various GNUnet-tools as
1986 your "normal" user (who should only be in the group 'gnunet').
