+Installation
+############
+
+Compiling
+*********
+
+The library uses c++11 and requires `Boost <http://www.boost.org/>`_ with version
+1.48.0 or more recent. It is a multi-platform library and compiles on Linux,
+Mac OSX and Visual Studio 2015.
+It also requires cmake to generate makefiles, and cython to compile the
+library.
+
+Demos and examples
+==================
+
+To build the demos and examples, run the following commands in a terminal:
+
+.. code-block:: bash
+
+    cd /path-to-gudhi/
+    mkdir build
+    cd build/
+    cmake ..
+    make cython
+
+A list of examples is available here.
+
+Test suites
+===========
+
+To test your build, `py.test <http://doc.pytest.org>`_ is required. Run the
+following command in a terminal:
+
+.. code-block:: bash
+
+    cd /path-to-gudhi/build/src/cython
+    # For windows, you have to set PYTHONPATH environment variable
+    export PYTHONPATH='$PYTHONPATH:/path-to-gudhi/build/src/cython'
+    py.test
+
+Documentation
+=============
+
+To build the documentation, `sphinx-doc <http://http://www.sphinx-doc.org>`_ is
+required. Run the following commands in a terminal:
+
+.. code-block:: bash
+
+    make sphynx
+
+Optional third-party library
+****************************
+
+CGAL
+====
+
+The :doc:`Alpha complex </alpha_complex_user>` data structure and
+:doc:`Tangential complex </tangential_complex_user>` data structures,
+:doc:`Bottleneck distance </bottleneck_distance_user>`requires CGAL, which is a
+C++ library which provides easy access to efficient and reliable geometric
+algorithms.
+
+Having CGAL version 4.7.0 or higher installed is recommended. The procedure to
+install this library according to your operating system is detailed
+`here <http://doc.cgal.org/latest/Manual/installation.html>`_.
+
+The following examples require the Computational Geometry Algorithms Library:
+
+* alpha_complex_diagram_persistence_from_off_file_example.py
+* alpha_complex_from_points_example.py
+
+The following example requires CGAL version ≥ 4.8.0:
+
+* bottleneck_basic_example.py
+* tangential_complex_plain_homology_from_off_file_example.py
+
+Eigen3
+======
+
+The :doc:`Alpha complex </alpha_complex_user>` and
+:doc:`Tangential complex </tangential_complex_user>` data structures and few
+examples requires `Eigen3 <http://eigen.tuxfamily.org/>`_, a C++ template
+library for linear algebra: matrices, vectors, numerical solvers, and related
+algorithms.
+
+The following examples require the `Eigen3 <http://eigen.tuxfamily.org/>`_:
+
+* alpha_complex_diagram_persistence_from_off_file_example.py
+* alpha_complex_from_points_example.py
+* tangential_complex_plain_homology_from_off_file_example.py
+
+Matplotlib
+==========
+
+The :doc:`persistence graphical tools </persistence_graphical_tools_user>`
+module requires `Matplotlib <http://matplotlib.org>`_, a Python 2D plotting
+library which produces publication quality figures in a variety of hardcopy
+formats and interactive environments across platforms.
+
+The following examples require the `Matplotlib <http://matplotlib.org>`_:
+
+* alpha_complex_diagram_persistence_from_off_file_example.py
+* gudhi_graphical_tools_example.py
+* periodic_cubical_complex_barcode_persistence_from_perseus_file_example.py
+* rips_complex_diagram_persistence_with_pandas_interface_example.py
+* rips_persistence_diagram.py
+* tangential_complex_plain_homology_from_off_file_example.py
+
+Numpy
+=====
+
+The :doc:`persistence graphical tools </persistence_graphical_tools_user>`
+module requires `NumPy <http://numpy.org>`_, a fundamental package for
+scientific computing with Python.
+
+The following examples require the `NumPy <http://numpy.org>`_:
+
+* alpha_complex_diagram_persistence_from_off_file_example.py
+* gudhi_graphical_tools_example.py
+* periodic_cubical_complex_barcode_persistence_from_perseus_file_example.py
+* rips_complex_diagram_persistence_with_pandas_interface_example.py
+* rips_persistence_diagram.py
+* tangential_complex_plain_homology_from_off_file_example.py
