1825 Please make sure NOW that you have created a user and group 'gnunet'
1826 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux, type:
1827         addgroup gnunetdns
1828         adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1829
1830 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1831 'gnunet'.  Then, you can compile GNUnet with
1832         make
1833
1834 After that, run (if necessary as 'root')
1835         make install
1836 to install everything.
1837
1838 Each GNUnet user should be added to the 'gnunet' group (may
1839 require fresh login to come into effect):
1840         adduser USERNAME gnunet
1841 (run the above command as root once for each of your users, replacing
1842 "USERNAME" with the respective login names).  If you have a global IP
1843 address, no further configuration is required.
1844
1845 For more detailed setup instructions, see https://gnunet.org/installation
1846
1847 Optionally, download and compile gnunet-gtk to get a GUI for
1848 file-sharing and configuration.  This is particularly recommended
1849 if your network setup is non-trivial, as gnunet-setup can be
1850 used to test in the GUI if your network configuration is working.
1851 gnunet-setup should be run as the "gnunet" user under X.  As it
1852 does very little with the network, running it as "root" is likely
1853 also harmless.  You can also run it as a normal user, but then
1854 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
1855 home directory in the end.
1856
1857 Once you have configured your peer, run (as the 'gnunet' user)
1858         gnunet-arm -s
1859 to start the peer.  You can then run the various GNUnet-tools as
1860 your "normal" user (who should only be in the group 'gnunet').
