+In this tutorial we will use Geant4 version 11.2.0, compiled with the support of multithreading, GDML and Qt5 based Gui.
 
 On Linux systems we use a compiled version of Geant4 and a binary distribution for ROOT installations.
 
 Below we provide detailed instructions for the installation on Ubuntu 20.04.
 The installation for other Debian and Ubuntu like Linux'es will be similar but the names of libraries can be slightly different. On Linux you can use GNU *c++*, *clang* or Intel *icc* compilers, we describe only the GNU *g++* installation.
 
-The installation was tested on VirtualBox VM running *Ubuntu 20.04* and Windows 10 WLS2 *Ubuntu 20.04* application.

 Some dependancies like kerberos and mysql were dropped because we do not use these features in the tutorial.
 The libraries which we need for Geant4 compilation need to be installed first. For this, the `ubuntu20_deps.sh` script is provided on the Ubuntu 20.04 server. This script must be executed only once.
