1804 Please make sure NOW that you have created a user and group 'gnunet'
1805 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux, type:
1806         addgroup gnunetdns
1807         adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1808
1809 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1810 'gnunet'.  Then, you can compile GNUnet with
1811         make
1812
1813 After that, run (if necessary as 'root')
1814         make install
1815 to install everything.
1816
1817 Each GNUnet user should be added to the 'gnunet' group (may
1818 require fresh login to come into effect):
1819         adduser USERNAME gnunet
1820 (run the above command as root once for each of your users, replacing
1821 "USERNAME" with the respective login names).  If you have a global IP
1822 address, no further configuration is required.
1823
1824 For more detailed setup instructions, see https://gnunet.org/installation
1825
1826 Optionally, download and compile gnunet-gtk to get a GUI for
1827 file-sharing and configuration.  This is particularly recommended
1828 if your network setup is non-trivial, as gnunet-setup can be
1829 used to test in the GUI if your network configuration is working.
1830 gnunet-setup should be run as the "gnunet" user under X.  As it
1831 does very little with the network, running it as "root" is likely
1832 also harmless.  You can also run it as a normal user, but then
1833 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
1834 home directory in the end.
1835
1836 Once you have configured your peer, run (as the 'gnunet' user)
1837         gnunet-arm -s
1838 to start the peer.  You can then run the various GNUnet-tools as
1839 your "normal" user (who should only be in the group 'gnunet').
