1961 IMPORTANT:
1962
1963 Please make sure NOW that you have created a user and group 'gnunet'
1964 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
1965 type:
1966
1967   addgroup gnunetdns
1968   adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1969
1970 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1971 'gnunet'.  Then, you can compile GNUnet with
1972
1973   make
1974
1975 After that, run (if necessary as 'root')
1976
1977   make install
1978
1979 to install everything.
1980
1981 Each GNUnet user should be added to the 'gnunet' group (may
1982 require fresh login to come into effect):
1983
1984   adduser USERNAME gnunet
1985
1986 (run the above command as root once for each of your users, replacing
1987 "USERNAME" with the respective login names).  If you have a global IP
1988 address, no further configuration is required.
1989
1990 For more detailed setup instructions, see https://docs.gnunet.org/
1991
1992 Optionally, download and compile gnunet-gtk to get a GUI for
1993 file-sharing and configuration.  This is particularly recommended
1994 if your network setup is non-trivial, as gnunet-setup can be
1995 used to test in the GUI if your network configuration is working.
1996 gnunet-setup should be run as the "gnunet" user under X.  As it
1997 does very little with the network, running it as "root" is likely
1998 also harmless.  You can also run it as a normal user, but then
1999 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2000 home directory in the end.
2001
2002 Once you have configured your peer, run (as the 'gnunet' user)
2003
2004   gnunet-arm -s
2005
2006 to start the peer.  You can then run the various GNUnet-tools as
