2001 Please make sure NOW that you have created a user and group 'gnunet'
2002 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux, type:
2003         addgroup gnunetdns
2004         adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2005
2006 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2007 'gnunet'.  Then, you can compile GNUnet with
2008         make
2009
2010 After that, run (if necessary as 'root')
2011         make install
2012 to install everything.
2013
2014 Each GNUnet user should be added to the 'gnunet' group (may
2015 require fresh login to come into effect):
2016         adduser USERNAME gnunet
2017 (run the above command as root once for each of your users, replacing
2018 "USERNAME" with the respective login names).  If you have a global IP
2019 address, no further configuration is required.
2020
2021 For more detailed setup instructions, see https://gnunet.org/installation
2022
2023 Optionally, download and compile gnunet-gtk to get a GUI for
2024 file-sharing and configuration.  This is particularly recommended
2025 if your network setup is non-trivial, as gnunet-setup can be
2026 used to test in the GUI if your network configuration is working.
2027 gnunet-setup should be run as the "gnunet" user under X.  As it
2028 does very little with the network, running it as "root" is likely
2029 also harmless.  You can also run it as a normal user, but then
2030 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2031 home directory in the end.
2032
2033 Once you have configured your peer, run (as the 'gnunet' user)
2034         gnunet-arm -s
2035 to start the peer.  You can then run the various GNUnet-tools as
2036 your "normal" user (who should only be in the group 'gnunet').
