1988 Please make sure NOW that you have created a user and group 'gnunet'
1989 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux, type:
1990         addgroup gnunetdns
1991         adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1992
1993 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1994 'gnunet'.  Then, you can compile GNUnet with
1995         make
1996
1997 After that, run (if necessary as 'root')
1998         make install
1999 to install everything.
2000
2001 Each GNUnet user should be added to the 'gnunet' group (may
2002 require fresh login to come into effect):
2003         adduser USERNAME gnunet
2004 (run the above command as root once for each of your users, replacing
2005 "USERNAME" with the respective login names).  If you have a global IP
2006 address, no further configuration is required.
2007
2008 For more detailed setup instructions, see https://gnunet.org/installation
2009
2010 Optionally, download and compile gnunet-gtk to get a GUI for
2011 file-sharing and configuration.  This is particularly recommended
2012 if your network setup is non-trivial, as gnunet-setup can be
2013 used to test in the GUI if your network configuration is working.
2014 gnunet-setup should be run as the "gnunet" user under X.  As it
2015 does very little with the network, running it as "root" is likely
2016 also harmless.  You can also run it as a normal user, but then
2017 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2018 home directory in the end.
2019
2020 Once you have configured your peer, run (as the 'gnunet' user)
2021         gnunet-arm -s
2022 to start the peer.  You can then run the various GNUnet-tools as
2023 your "normal" user (who should only be in the group 'gnunet').
