1820 Please make sure NOW that you have created a user and group 'gnunet'
1821 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux, type:
1822         addgroup gnunetdns
1823         adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1824
1825 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1826 'gnunet'.  Then, you can compile GNUnet with
1827         make
1828
1829 After that, run (if necessary as 'root')
1830         make install
1831 to install everything.
1832
1833 Each GNUnet user should be added to the 'gnunet' group (may
1834 require fresh login to come into effect):
1835         adduser USERNAME gnunet
1836 (run the above command as root once for each of your users, replacing
1837 "USERNAME" with the respective login names).  If you have a global IP
1838 address, no further configuration is required.
1839
1840 For more detailed setup instructions, see https://gnunet.org/installation
1841
1842 Optionally, download and compile gnunet-gtk to get a GUI for
1843 file-sharing and configuration.  This is particularly recommended
1844 if your network setup is non-trivial, as gnunet-setup can be
1845 used to test in the GUI if your network configuration is working.
1846 gnunet-setup should be run as the "gnunet" user under X.  As it
1847 does very little with the network, running it as "root" is likely
1848 also harmless.  You can also run it as a normal user, but then
1849 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
1850 home directory in the end.
1851
1852 Once you have configured your peer, run (as the 'gnunet' user)
1853         gnunet-arm -s
1854 to start the peer.  You can then run the various GNUnet-tools as
1855 your "normal" user (who should only be in the group 'gnunet').
