2048
2049 Make sure that '/var/lib/gnunet' is owned (and writable) by user

2051         make
2052
2053 After that, run (if necessary as 'root')
2054         make install
2055 to install everything.

2057 Each GNUnet user should be added to the 'gnunet' group (may

2068 if your network setup is non-trivial, as gnunet-setup can be
2069 used to test in the GUI if your network configuration is working.
2070 gnunet-setup should be run as the "gnunet" user under X.  As it
2071 does very little with the network, running it as "root" is likely
2072 also harmless.  You can also run it as a normal user, but then
2073 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2074 home directory in the end.
2075
2076 Once you have configured your peer, run (as the 'gnunet' user)
2077         gnunet-arm -s
2078 to start the peer.  You can then run the various GNUnet-tools as
2079 your "normal" user (who should only be in the group 'gnunet').
