1983 Please make sure NOW that you have created a user and group 'gnunet'
1984 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux, type:
1985         addgroup gnunetdns
1986         adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1987
1988 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1989 'gnunet'.  Then, you can compile GNUnet with
1990         make
1991
1992 After that, run (if necessary as 'root')
1993         make install
1994 to install everything.
1995
1996 Each GNUnet user should be added to the 'gnunet' group (may
1997 require fresh login to come into effect):
1998         adduser USERNAME gnunet
1999 (run the above command as root once for each of your users, replacing
2000 "USERNAME" with the respective login names).  If you have a global IP
2001 address, no further configuration is required.
2002
2003 For more detailed setup instructions, see https://gnunet.org/installation
2004
2005 Optionally, download and compile gnunet-gtk to get a GUI for
2006 file-sharing and configuration.  This is particularly recommended
2007 if your network setup is non-trivial, as gnunet-setup can be
2008 used to test in the GUI if your network configuration is working.
2009 gnunet-setup should be run as the "gnunet" user under X.  As it
2010 does very little with the network, running it as "root" is likely
2011 also harmless.  You can also run it as a normal user, but then
2012 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2013 home directory in the end.
2014
2015 Once you have configured your peer, run (as the 'gnunet' user)
2016         gnunet-arm -s
2017 to start the peer.  You can then run the various GNUnet-tools as
2018 your "normal" user (who should only be in the group 'gnunet').
