1808 Please make sure NOW that you have created a user and group 'gnunet'
1809 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux, type:
1810         addgroup gnunetdns
1811         adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1812
1813 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1814 'gnunet'.  Then, you can compile GNUnet with
1815         make
1816
1817 After that, run (if necessary as 'root')
1818         make install
1819 to install everything.
1820
1821 Each GNUnet user should be added to the 'gnunet' group (may
1822 require fresh login to come into effect):
1823         adduser USERNAME gnunet
1824 (run the above command as root once for each of your users, replacing
1825 "USERNAME" with the respective login names).  If you have a global IP
1826 address, no further configuration is required.
1827
1828 For more detailed setup instructions, see https://gnunet.org/installation
1829
1830 Optionally, download and compile gnunet-gtk to get a GUI for
1831 file-sharing and configuration.  This is particularly recommended
1832 if your network setup is non-trivial, as gnunet-setup can be
1833 used to test in the GUI if your network configuration is working.
1834 gnunet-setup should be run as the "gnunet" user under X.  As it
1835 does very little with the network, running it as "root" is likely
1836 also harmless.  You can also run it as a normal user, but then
1837 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
1838 home directory in the end.
1839
1840 Once you have configured your peer, run (as the 'gnunet' user)
1841         gnunet-arm -s
1842 to start the peer.  You can then run the various GNUnet-tools as
1843 your "normal" user (who should only be in the group 'gnunet').
