2114 Optionally, download and compile gnunet-gtk to get a GUI for
2115 file-sharing and configuration.  This is particularly recommended
2116 if your network setup is non-trivial, as gnunet-setup can be
2117 used to test in the GUI if your network configuration is working.
2118 gnunet-setup should be run as the "gnunet" user under X.  As it
2119 does very little with the network, running it as "root" is likely
2120 also harmless.  You can also run it as a normal user, but then
2121 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2122 home directory in the end.
2123
2124 Once you have configured your peer, run (as the 'gnunet' user)
2125         gnunet-arm -s
2126 to start the peer.  You can then run the various GNUnet-tools as
2127 your "normal" user (who should only be in the group 'gnunet').
