		<h2 id="overview">Overview</h2>
		<p>WinPython is a free open-source portable distribution of the <a href="https://www.python.org/">Python programming language</a> for Windows Vista/7/8 and scientific and educational usage.</p>pa
		<p><img style="width: 901px; height: 97px;" alt="WinPython Launcher Icons" src="images/winpython_launchers_2741.png" /></p>
		<p>It is a full-featured (see what's inside <a href="https://github.com/winpython/winpython/blob/master/changelogs/WinPython-2.7.8.2.txt">WinPython 2.7</a>, <a href="https://github.com/winpython/winpython/blob/master/changelogs/WinPython-3.3.5.1.txt">WinPython 3.3</a> or <a href="https://github.com/winpython/winpython/blob/master/changelogs/WinPython-3.4.2.1.txt">WinPython 3.4</a>) Python-based scientific environment:</p>
		<ul>
			<li>Designed for scientists, data-scientists, and education (thanks to <a href="http://numpy.org/">NumPy</a>, <a href="https://www.scipy.org/">SciPy</a>, <a href="https://www.sympy.org/">Sympy</a>, <a href="http://www.matplotlib.org/">Matplotlib</a>, <a href="http://pandas.pydata.org/">Pandas</a>, <a href="https://code.google.com/p/guiqwt/">guiqwt</a>, etc.):
			<ul>
				<li>Regular <strong>scientific users</strong>: interactive data processing and visualization using Python with <a href="https://code.google.com/p/spyderlib/">Spyder</a> </li>
				<li><strong>Advanced scientific users and software developers</strong>: Python applications development with <a href="https://code.google.com/p/spyderlib/">Spyder</a>, version control with Mercurial and other development tools (like gettext, etc.)</li>
			</ul></li>
			<li><strong>Portable</strong>:
			<ul>
				<li>Runs out of the box on any Windows with 2GB Ram (IPython needs Windows>XP, and IPython Notebook a recent browser)</li>
                <li>The WinPython folder can be moved to any location (local, network, USB drive) with most of the <a href="https://github.com/winpython/winpython/wiki/Installation#settings">application settings</a></li>
            </ul>
			<li><strong>Flexible</strong>: 
			<ul>
				<li>You can install as many WinPython distributions as you want on the same machine: each one is isolated and self-consistent</li>
				<li>These installations can be of different versions of Python (2.7, 3.3 or 3.4) or different architectures (32bit or 64bit)</li>
            </ul>
			<li><strong>Customizable</strong>:
			<ul>
				<li>The integrated WinPython Package Manager (<a href="https://sourceforge.net/p/winpython/wiki/WPPM"><!-- TODO -->WPPM</a>) helps installing, uninstalling or upgrading Python packages  </li>
				<li>It's also possible to install or upgrade packages using <tt>pip</tt> from the WinPython command prompt </li>
				<li>A configuration file allows you to set <a href="https://sourceforge.net/p/winpython/wiki/Environment"><!-- TODO -->environment variables</a> at runtime </li>
			</ul></li>
		</ul>
		<p>WinPython is <strong>something different</strong> from other Python Distributions (see historic <a href="https://sourceforge.net/p/winpython/wiki/Roadmap"><!-- TODO --> motivation and concept</a>):</p>
		<ul>
			<li><strong>non-invasive</strong>: WinPython lives entirely in its own directory, without any OS installation</li>
			<li><strong>flavors</strong>: releases with added packages are created to better fit a <a href="https://sourceforge.net/projects/stonebig.u/files/Winpython_flavors/">domain</a> out-of-the-box</li>
			<li><strong>do your own flavor</strong>: a winpython-creator <a href="https://sourceforge.net/projects/stonebig.u/files/Do_It_Yourself/">kit</a> is made available for you</li>
		</ul>

		<h2 id="portable">Portable or not, the choice is yours!</h2>
		<p>WinPython is a portable application, so the user should not expect any integration into Windows explorer during <a href="https://github.com/winpython/winpython/wiki/Installation">installation</a>. However, the <a href="https://sourceforge.net/p/winpython/wiki/ControlPanel"><!-- TODO -->WinPython Control Panel</a> allows to "register" your distribution to Windows (see screenshot below).</p>
		<p><img style="width: 453px; height: 152px;" alt="WinPython Register" src="images/wpcp_register_2741.png" /></p>
		<p>Registering your WinPython installation will:</p>
		<ul>
			<li>associate file extensions <tt>.py</tt>, <tt>.pyc</tt> and <tt>.pyo</tt> to Python interpreter</li>
			<li>register Python icons in Windows explorer</li>
			<li>add context menu entries <tt>Edit with IDLE</tt> and <tt>Edit with Spyder</tt> for <tt>.py</tt> files</li>
			<li>register WinPython as a standard Python distribution (standard Python Windows installers will see WinPython in Windows registry)</li>
		</ul>
		That is exactly what the official Python installer would do to your machine: in other words, you can have it both ways!
