+You may install PSpaMM as a Python package.
 
 .. code-block:: bash
 
-   git clone https://github.com/SeisSol/PSpaMM.git
-   # make sure $HOME/bin exists or create it with "mkdir ~/bin"
-   ln -s $(pwd)/PSpaMM/pspamm.py $HOME/bin/pspamm.py
-   
-Instead of linking, you could also add the following line to your .bashrc:
-
-.. code-block:: bash
