-While pyMOR itself is written in pure Python (with the exception of few `Cython
-<http://cython.org>`_ extension modules) and does not really require
-installation, it depends on several Python packages in recent versions (most
-notably `NumPy <http://www.numpy.org>`_, `SciPy <http://www.scipy.org>`_,
-`matplotlib <http://matplotlib.org>`_ and `PySide <http//www.pyside.org>`_)
-which are not so easy to install. For this reason we provide an installation
-script which will install all dependencies into a dedicated `virtualenv
-<http://virtualenv.org>`_. It will also install pyMOR itself into the
-virtualenv or add the repository to its ``PYTHONPATH``. For further details
-please refer to the `README
-<https://github.com/pymor/pymor/blob/master/README.markdown>`_ file in the
-pyMOR repository.
+Daily snapshots can be installed by using the ``pymor/daily`` PPA instead of
+``pymor/stable``. The current release can also be installed via `pip
+<http://pip-installer.org>`. Please take a look at our `README
+<https://github.com/pyMor/pyMor#installation-into-a-virtualenv>` file for
+further details. The `README
+<https://github.com/pyMor/pyMor#setting-up-an-environment-for-pymor-development>`
+also contains instructions for setting up a development environment for working
+on pyMOR itself.

+The demo scripts can also be directly launched from the source tree::

 This will solve and reduce the so called thermalblock problem using
 the reduced basis method with a greedy basis generation algorithm.
