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