2181 IMPORTANT:
2182
2183 Please make sure NOW that you have created a user and group 'gnunet'
2184 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2185 type:
2186
2187   addgroup gnunetdns
2188   adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2189
2190 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2191 'gnunet'.  Then, you can compile GNUnet with
2192
2193   make
2194
2195 After that, run (if necessary as 'root')
2196
2197   make install
2198
2199 to install everything.
2200
2201 Each GNUnet user should be added to the 'gnunet' group (may
2202 require fresh login to come into effect):
2203
2204   adduser USERNAME gnunet
2205
2206 (run the above command as root once for each of your users, replacing
2207 "USERNAME" with the respective login names).  If you have a global IP
2208 address, no further configuration is required.
2209
2210 For more detailed setup instructions, see https://docs.gnunet.org/
2211
2212 Optionally, download and compile gnunet-gtk to get a GUI for
2213 file-sharing and configuration.  This is particularly recommended
2214 if your network setup is non-trivial, as gnunet-setup can be
2215 used to test in the GUI if your network configuration is working.
2216 gnunet-setup should be run as the "gnunet" user under X.  As it
2217 does very little with the network, running it as "root" is likely
2218 also harmless.  You can also run it as a normal user, but then
2219 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2220 home directory in the end.
2221
2222 Once you have configured your peer, run (as the 'gnunet' user)
2223
2224   gnunet-arm -s
2225
2226 to start the peer.  You can then run the various GNUnet-tools as
2227 your "normal" user (who should only be in the group 'gnunet').
