+The safest way is to execute the automatic installation by using the configure shell script. One should go to the geant4.version/ directory and first build the libraries. Type
+<PRE>
+./Configure -build
+</PRE>
+and follow the instructions. Each question must be answered <B><I>very carefully</I></B> in order to get a good configuration<A HREF="http://hep.ucsb.edu/people/joel/geant4.html"><SUP>tip</SUP></A>.
+
+Before going any further, make sure that the @ref clheplibs "CLHEP environment variables" are properly set. Remember that the values of the library directory and name can be obtained by entering <tt>./clheplib</tt> in <tt>CLHEP/bin</tt>.
+The environment variables for the visualization drivers shall also be set at this point.
+Finally, it is recommended to run the script <tt>geant4.version/.config/bin/Linux-g++/env.sh</tt> as a confirmation (it should have been ran automatically after the configuration script of the previous command).
+Then execute
+<PRE>
+./Configure -install
+</PRE> 
+And compile the source code
+<PRE>
+cd geant4.version/source
+gmake
+</PRE>
+The \gf code is now ready to use and one can compile an example to check that it runs correctly.
+
+It is usefull to launch the \gf environment variables script <tt>geant4.version/.config/bin/Linux-g++/env.sh</tt> via the SetEnv.sh script.

+<H4><A>Manual way:</A></H4>
+First, some environement variables must be set (for example):
+<PRE>
+export G4INSTALL=/home/user/geant4.version   
+export G4SYSTEM=Linux-g++ (for example)
+export CLHEP\_BASE\_DIR=/home/user/CLHEP
+</PRE>
+Then the other variables should be set executing the $G4INSTALL/Configure file. 
+
+<P>
+Changes of the configuration can be done directly, editing the config.sh file which is located in the $G4INSTALL/.config/bin/Linux-g++ directory.
+After modification, this executed in order to prepare the compilation.
+
+
+\anchor g4compile
+<H4><A>Compile Geant4:</A></H4>
+The compilation is launched by the command $G4INSTALL/source/gmake.
