-Installation
-============
-
-.. warning::
-
-    We advise installing virtualenv-1.9 or greater. Prior to version 1.9, the
-    pip included in virtualenv did not download from PyPI over SSL.
-
-.. warning::
-
-    When using pip to install virtualenv, we advise using pip 1.3 or greater.
-    Prior to version 1.3, pip did not download from PyPI over SSL.
-
-.. warning::
-
-    We advise against using easy_install to install virtualenv when using
-    setuptools < 0.9.7, because easy_install didn't download from PyPI over SSL
-    and was broken in some subtle ways.
-
-To install globally with `pip` (if you have pip 1.3 or greater installed globally):
-
-::
-
- $ [sudo] pip install virtualenv
-
-Or to get the latest unreleased dev version:
-
-::
-
- $ [sudo] pip install https://github.com/pypa/virtualenv/tarball/develop
-
-
-To install version X.X globally from source:
-
-::
-
- $ curl -O https://pypi.python.org/packages/source/v/virtualenv/virtualenv-X.X.tar.gz
- $ tar xvfz virtualenv-X.X.tar.gz
- $ cd virtualenv-X.X
- $ [sudo] python setup.py install
-
-
-To *use* locally from source:
-
-::
-
- $ curl -O https://pypi.python.org/packages/source/v/virtualenv/virtualenv-X.X.tar.gz
- $ tar xvfz virtualenv-X.X.tar.gz
- $ cd virtualenv-X.X
- $ python virtualenv.py myVE
-
-.. note::
-
-    The ``virtualenv.py`` script is *not* supported if run without the
-    necessary pip/setuptools/virtualenv distributions available locally. All
-    of the installation methods above include a ``virtualenv_support``
-    directory alongside ``virtualenv.py`` which contains a complete set of
-    pip and setuptools distributions, and so are fully supported.
