 ===========================================
  IPython: Productive Interactive Computing
 ===========================================
 
 Overview
 ========
 
 Welcome to IPython.  Our full documentation is available on `our website
 <http://ipython.org/documentation.html>`_; if you downloaded a built source
 distribution the ``docs/source`` directory contains the plaintext version of
 these manuals.  If you have Sphinx installed, you can build them by typing
 ``cd docs; make html`` for local browsing.
 
 
 See the `install page <http://ipython.org/install.html>`__ to install IPython.
 
 The Notebook, Qt console and a number of other pieces are now parts of *Jupyter*.
 See the `Jupyter installation docs <http://jupyter.readthedocs.org/en/latest/install.html>`__
 if you want to use these.
 
 Officially, IPython requires Python version 2.7, or 3.3 and above.
 IPython 1.x is the last IPython version to support Python 2.6 and 3.2.
 
 
 Instant running
 ===============
 
 You can run IPython from this directory without even installing it system-wide
 by typing at the terminal::
 
    $ python -m IPython
