+You can compile GNUnet with
+	make
+now. After that, run (if necessary as 'root')
+        make install
+to install everything. You may want to create a new user account
+to run the GNUnet service:
+	adduser gnunet
+You also need to create an configuration file that should
+specify the path where GNUnet should store data.  For example,
+you could store in "/etc/gnunet.conf" the following lines:
+
+[[PATHS]]
+SERVICEHOME = /var/lib/gnunet
+DEFAULTCONFIG = /etc/gnunet.conf
+
+Now, in order to start your peer, run as the 'gnunet' user
+	gnunet-arm -s
+
+Each GNUnet user should also create an (at least initially) empty
+configuration file:
+	mkdir $HOME/.gnunet/
+	touch $HOME/.gnunet/gnunet.conf
+	
+Optionally, download and compile:
+- gnunet-gtk to get a GUI for file-sharing and configuration.
