1823 Please make sure NOW that you have created a user and group 'gnunet'
1824 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux, type:
1825         addgroup gnunetdns
1826         adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1827
1828 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1829 'gnunet'.  Then, you can compile GNUnet with
1830         make
1831
1832 After that, run (if necessary as 'root')
1833         make install
1834 to install everything.
1835
1836 Each GNUnet user should be added to the 'gnunet' group (may
1837 require fresh login to come into effect):
1838         adduser USERNAME gnunet
1839 (run the above command as root once for each of your users, replacing
1840 "USERNAME" with the respective login names).  If you have a global IP
1841 address, no further configuration is required.
1842
1843 For more detailed setup instructions, see https://gnunet.org/installation
1844
1845 Optionally, download and compile gnunet-gtk to get a GUI for
1846 file-sharing and configuration.  This is particularly recommended
1847 if your network setup is non-trivial, as gnunet-setup can be
1848 used to test in the GUI if your network configuration is working.
1849 gnunet-setup should be run as the "gnunet" user under X.  As it
1850 does very little with the network, running it as "root" is likely
1851 also harmless.  You can also run it as a normal user, but then
1852 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
1853 home directory in the end.
1854
1855 Once you have configured your peer, run (as the 'gnunet' user)
1856         gnunet-arm -s
1857 to start the peer.  You can then run the various GNUnet-tools as
1858 your "normal" user (who should only be in the group 'gnunet').
