2073         addgroup gnunetdns
2074         adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2075
2076 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2077 'gnunet'.  Then, you can compile GNUnet with
2078         make
2079
2080 After that, run (if necessary as 'root')
2081         make install
2082 to install everything.
2083
2084 Each GNUnet user should be added to the 'gnunet' group (may
2085 require fresh login to come into effect):
2086         adduser USERNAME gnunet
2087 (run the above command as root once for each of your users, replacing
2088 "USERNAME" with the respective login names).  If you have a global IP
2089 address, no further configuration is required.
2090
2091 For more detailed setup instructions, see https://docs.gnunet.org/
2092
2093 Optionally, download and compile gnunet-gtk to get a GUI for
2094 file-sharing and configuration.  This is particularly recommended
2095 if your network setup is non-trivial, as gnunet-setup can be
2096 used to test in the GUI if your network configuration is working.
2097 gnunet-setup should be run as the "gnunet" user under X.  As it
2098 does very little with the network, running it as "root" is likely
2099 also harmless.  You can also run it as a normal user, but then
2100 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2101 home directory in the end.
2102
2103 Once you have configured your peer, run (as the 'gnunet' user)
2104         gnunet-arm -s
2105 to start the peer.  You can then run the various GNUnet-tools as
2106 your "normal" user (who should only be in the group 'gnunet').
