 Installation
+============
+
+Dependencies
 ------------
 
-Source
-======
+LinPy requires Python version 3.4 or above to work.
 
-Users can install Linpy by cloning the git repository::
+LinPy's one mandatory dependency is isl version 0.12 or 0.13 (it may work with other versions of isl, but this has not been tested).
+isl can be downloaded `here <http://freshmeat.net/projects/isl/>`_ or preferably, using your favorite distribution's package manager.
+For Ubuntu, the command to run is::
 
-       git clone https://scm.cri.ensmp.fr/git/pypol.git
+    sudo apt-get install libisl-dev
 
-Install
-=======
+For Arch Linux, run::
 
-…execute `setup.py` 
+    sudo pacman -S isl
 
-Dependencies
-============
+Apart from isl, there are two optional dependencies that will maximize the use of LinPy's functions: `SymPy <http://sympy.org/en/index.html>`_ and `matplotlib <http://matplotlib.org/>`_.
+Please consult the `SymPy download page <http://sympy.org/en/download.html>`_ and `matplotlib installation instructions <http://matplotlib.org/faq/installing_faq.html#how-to-install>`_ to install these libraries.
 
-Linpy has several dependencies. Users will first need to install Integer Set Library (isl). The source files of isl are available as a tarball or a git repository. Both are available `here`_ .  
+pip

-To use the Linpy plotting function, users need to install matplotlib using instructions in the following `link`_.
+.. warning::
+
+    The project has not been published in PyPI yet, so this section is not relevant.
+    Instead, see the :ref:`source` section to install LinPy.
+
+LinPy can be installed using pip with the command::
+
+    sudo pip install linpy
