2009 Please make sure NOW that you have created a user and group 'gnunet'
2010 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux, type:
2011         addgroup gnunetdns
2012         adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2013
2014 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2015 'gnunet'.  Then, you can compile GNUnet with
2016         make
2017
2018 After that, run (if necessary as 'root')
2019         make install
2020 to install everything.
2021
2022 Each GNUnet user should be added to the 'gnunet' group (may
2023 require fresh login to come into effect):
2024         adduser USERNAME gnunet
2025 (run the above command as root once for each of your users, replacing
2026 "USERNAME" with the respective login names).  If you have a global IP
2027 address, no further configuration is required.
2028
2029 For more detailed setup instructions, see https://gnunet.org/installation
2030
2031 Optionally, download and compile gnunet-gtk to get a GUI for
2032 file-sharing and configuration.  This is particularly recommended
2033 if your network setup is non-trivial, as gnunet-setup can be
2034 used to test in the GUI if your network configuration is working.
2035 gnunet-setup should be run as the "gnunet" user under X.  As it
2036 does very little with the network, running it as "root" is likely
2037 also harmless.  You can also run it as a normal user, but then
2038 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2039 home directory in the end.
2040
2041 Once you have configured your peer, run (as the 'gnunet' user)
2042         gnunet-arm -s
2043 to start the peer.  You can then run the various GNUnet-tools as
2044 your "normal" user (who should only be in the group 'gnunet').
