2100 IMPORTANT:
2101
2102 Please make sure NOW that you have created a user and group 'gnunet'
2103 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2104 type:
2105
2106   addgroup gnunetdns
2107   adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2108
2109 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2110 'gnunet'.  Then, you can compile GNUnet with
2111
2112   make
2113
2114 After that, run (if necessary as 'root')
2115
2116   make install
2117
2118 to install everything.
2119
2120 Each GNUnet user should be added to the 'gnunet' group (may
2121 require fresh login to come into effect):
2122
2123   adduser USERNAME gnunet
2124
2125 (run the above command as root once for each of your users, replacing
2126 "USERNAME" with the respective login names).  If you have a global IP
2127 address, no further configuration is required.
2128
2129 For more detailed setup instructions, see https://docs.gnunet.org/
2130
2131 Optionally, download and compile gnunet-gtk to get a GUI for
2132 file-sharing and configuration.  This is particularly recommended
2133 if your network setup is non-trivial, as gnunet-setup can be
2134 used to test in the GUI if your network configuration is working.
2135 gnunet-setup should be run as the "gnunet" user under X.  As it
2136 does very little with the network, running it as "root" is likely
2137 also harmless.  You can also run it as a normal user, but then
2138 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2139 home directory in the end.
2140
2141 Once you have configured your peer, run (as the 'gnunet' user)
2142
2143   gnunet-arm -s
2144
2145 to start the peer.  You can then run the various GNUnet-tools as
2146 your "normal" user (who should only be in the group 'gnunet').
