-Installing MDAnalysis
-=====================
-
-The easiest approach to `install the latest release`_ is to use a package that
-can be installed either with conda_ or pip_.
-
-conda
------
-
-First installation with conda_:
-
-.. code-block:: bash
-
-   conda config --add channels conda-forge
-   conda install mdanalysis
-
-which will automatically install a *full set of dependencies*.
-
-To upgrade later:
-
-.. code-block:: bash
-
-   conda update mdanalysis
-
-pip
----
-
-Installation with `pip`_ and a *minimal set of dependencies*:
-
-.. code-block:: bash
-
-   pip install --upgrade MDAnalysis
-
-To install with a *full set of dependencies* (which includes everything needed
-for :mod:`MDAnalysis.analysis`), add the ``[analysis]`` tag:
-
-.. code-block:: bash
-
-   pip install --upgrade MDAnalysis[analysis]
-
-
-Tests
------
-
-If you want to `run the tests`_ or use example files to follow some of the
-examples in the documentation or the tutorials_, also install the
-``MDAnalysisTests`` package:
-
-.. code-block:: bash
-
-   conda install mdanalysistests            # with conda
-   pip install --upgrade MDAnalysisTests    # with pip
-
-.. _install the latest release:
