1931 Please make sure NOW that you have created a user and group 'gnunet'
1932 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux, type:
1933         addgroup gnunetdns
1934         adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1935
1936 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1937 'gnunet'.  Then, you can compile GNUnet with
1938         make
1939
1940 After that, run (if necessary as 'root')
1941         make install
1942 to install everything.
1943
1944 Each GNUnet user should be added to the 'gnunet' group (may
1945 require fresh login to come into effect):
1946         adduser USERNAME gnunet
1947 (run the above command as root once for each of your users, replacing
1948 "USERNAME" with the respective login names).  If you have a global IP
1949 address, no further configuration is required.
1950
1951 For more detailed setup instructions, see https://gnunet.org/installation
1952
1953 Optionally, download and compile gnunet-gtk to get a GUI for
1954 file-sharing and configuration.  This is particularly recommended
1955 if your network setup is non-trivial, as gnunet-setup can be
1956 used to test in the GUI if your network configuration is working.
1957 gnunet-setup should be run as the "gnunet" user under X.  As it
1958 does very little with the network, running it as "root" is likely
1959 also harmless.  You can also run it as a normal user, but then
1960 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
1961 home directory in the end.
1962
1963 Once you have configured your peer, run (as the 'gnunet' user)
1964         gnunet-arm -s
1965 to start the peer.  You can then run the various GNUnet-tools as
1966 your "normal" user (who should only be in the group 'gnunet').
