1944 Please make sure NOW that you have created a user and group 'gnunet'
1945 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux, type:
1946         addgroup gnunetdns
1947         adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1948
1949 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1950 'gnunet'.  Then, you can compile GNUnet with
1951         make
1952
1953 After that, run (if necessary as 'root')
1954         make install
1955 to install everything.
1956
1957 Each GNUnet user should be added to the 'gnunet' group (may
1958 require fresh login to come into effect):
1959         adduser USERNAME gnunet
1960 (run the above command as root once for each of your users, replacing
1961 "USERNAME" with the respective login names).  If you have a global IP
1962 address, no further configuration is required.
1963
1964 For more detailed setup instructions, see https://gnunet.org/installation
1965
1966 Optionally, download and compile gnunet-gtk to get a GUI for
1967 file-sharing and configuration.  This is particularly recommended
1968 if your network setup is non-trivial, as gnunet-setup can be
1969 used to test in the GUI if your network configuration is working.
1970 gnunet-setup should be run as the "gnunet" user under X.  As it
1971 does very little with the network, running it as "root" is likely
1972 also harmless.  You can also run it as a normal user, but then
1973 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
1974 home directory in the end.
1975
1976 Once you have configured your peer, run (as the 'gnunet' user)
1977         gnunet-arm -s
1978 to start the peer.  You can then run the various GNUnet-tools as
1979 your "normal" user (who should only be in the group 'gnunet').
