2010 Please make sure NOW that you have created a user and group 'gnunet'
2011 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux, type:
2012         addgroup gnunetdns
2013         adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2014
2015 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2016 'gnunet'.  Then, you can compile GNUnet with
2017         make
2018
2019 After that, run (if necessary as 'root')
2020         make install
2021 to install everything.
2022
2023 Each GNUnet user should be added to the 'gnunet' group (may
2024 require fresh login to come into effect):
2025         adduser USERNAME gnunet
2026 (run the above command as root once for each of your users, replacing
2027 "USERNAME" with the respective login names).  If you have a global IP
2028 address, no further configuration is required.
2029
2030 For more detailed setup instructions, see https://gnunet.org/installation
2031
2032 Optionally, download and compile gnunet-gtk to get a GUI for
2033 file-sharing and configuration.  This is particularly recommended
2034 if your network setup is non-trivial, as gnunet-setup can be
2035 used to test in the GUI if your network configuration is working.
2036 gnunet-setup should be run as the "gnunet" user under X.  As it
2037 does very little with the network, running it as "root" is likely
2038 also harmless.  You can also run it as a normal user, but then
2039 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2040 home directory in the end.
2041
2042 Once you have configured your peer, run (as the 'gnunet' user)
2043         gnunet-arm -s
2044 to start the peer.  You can then run the various GNUnet-tools as
2045 your "normal" user (who should only be in the group 'gnunet').
