1922 Please make sure NOW that you have created a user and group 'gnunet'
1923 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux, type:
1924         addgroup gnunetdns
1925         adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1926
1927 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1928 'gnunet'.  Then, you can compile GNUnet with
1929         make
1930
1931 After that, run (if necessary as 'root')
1932         make install
1933 to install everything.
1934
1935 Each GNUnet user should be added to the 'gnunet' group (may
1936 require fresh login to come into effect):
1937         adduser USERNAME gnunet
1938 (run the above command as root once for each of your users, replacing
1939 "USERNAME" with the respective login names).  If you have a global IP
1940 address, no further configuration is required.
1941
1942 For more detailed setup instructions, see https://gnunet.org/installation
1943
1944 Optionally, download and compile gnunet-gtk to get a GUI for
1945 file-sharing and configuration.  This is particularly recommended
1946 if your network setup is non-trivial, as gnunet-setup can be
1947 used to test in the GUI if your network configuration is working.
1948 gnunet-setup should be run as the "gnunet" user under X.  As it
1949 does very little with the network, running it as "root" is likely
1950 also harmless.  You can also run it as a normal user, but then
1951 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
1952 home directory in the end.
1953
1954 Once you have configured your peer, run (as the 'gnunet' user)
1955         gnunet-arm -s
1956 to start the peer.  You can then run the various GNUnet-tools as
1957 your "normal" user (who should only be in the group 'gnunet').
