 Getting Started
 ===============
 
 .. |lm| replace:: *LibMultiScale*
 
 Dependencies
 ------------
 
 For `Debian bullseye <https://www.debian.org/releases/bullseye/>`_ ,
 `Ubuntu 19.10 (Eoan Ermine) <https://releases.ubuntu.com/19.10/>`_ ,
 and
 `Ubuntu 20.04 (Focal Fossa) <https://releases.ubuntu.com/20.04/>`_ 
 the necessary dependencies can be installed with
 
 .. code-block:: bash
 
-  apt-get -qq update && apt-get install -y cmake build-essential python3-dev python3-numpy libboost-dev libfftw3-dev libgsl-dev gfortran liblapack-dev libopenmpi-dev sharutils git doxygen graphviz python3-pip texlive-latex-base libmumps-dev libscotch-dev
+  sudo apt-get -qq update && sudo apt-get install -y cmake build-essential python3-dev python3-numpy libboost-dev libfftw3-dev libgsl-dev gfortran liblapack-dev libopenmpi-dev sharutils git doxygen graphviz python3-pip texlive-latex-base libmumps-dev libscotch-dev
 
 In order to be able to generate the documentation the following may be issued
 
 .. code-block:: bash
 
-  apt-get install -y git doxygen graphviz python3-pip texlive-latex-base
-  pip3 install sphinx breathe sphinx-rtd-theme
+  sudo apt-get install -y git doxygen graphviz python3-pip texlive-latex-base
+  pip3 install --user sphinx breathe sphinx-rtd-theme
 
 Getting source code
 -------------------
 
 |lm| source code can be downloaded from the gitlab repository:
 
 .. code-block:: bash
 
    git clone https://gitlab.com/libmultiscale/libmultiscale.git
 
 
 Fetching the submodules
 -----------------------
 
 In order to prepare for the compilation, several submodules are required:
 
 .. code-block:: bash
 		
   git submodule update --init third-party/eigen
 
 And to activate the *molecular dynamics*, *finite elements* and *dislocation
 dynamics* plugins, other submodules have to be activated:
 
 .. code-block:: bash
 
   # Akantu finite element support
   git submodule update --init third-party/akantu
 
   # Lammps molecular dynamics support
   git submodule update --init third-party/lammps
 
   # ParaDiS discrete dislocation dynamics support
   git submodule update --init third-party/paradis
 
 
 Compiling
 ---------
 
 |lm| is a *cmake* project. Therefore to configure it you can either follow the usual way:
 
 .. code-block:: bash
 
    cd libmultiscale
    mkdir build
    cd build
    ccmake <path to libmultiscale sources>
 
 *[ Set the options that you need ]*
 
 Setting the option at the command line is possible by specifying the activated options
 
 .. code-block:: bash
 
    cmake -DCMAKE_BUILD_TYPE:STRING=Release -DLIBMULTISCALE_MD1D:BOOL=ON -DLIBMULTISCALE_MECA1D:BOOL=ON -DLIBMULTISCALE_LAMMPS_PLUGIN:BOOL=ON -DLIBMULTISCALE_AKANTU_PLUGIN:BOOL=ON -DLIBMULTISCALE_PARADIS_PLUGIN:BOOL=ON -DLIBMULTISCALE_DOCUMENTATION:BOOL=ON ..
 
 .. code-block:: bash
 		
    make
    make install
