+Installation
+============
+
+.. _pipinstall:
+
+Installing with pip
+-------------------
+
+These instructions cover installation with the ``pip`` package
+management tool.  This will install fermipy and its dependencies into
+your python distribution.
+
+Before starting the installation process, you will need to determine
+whether you have setuptools and pip installed in your local python
+environment.  You may need to install these packages if you are
+running with the binary version of the Fermi Science Tools distributed
+by the FSSC.  The following command will install both packages in your
+local environment:
+
+.. code-block:: bash
+
+   $ curl https://bootstrap.pypa.io/get-pip.py | python -
+
+Check if pip is correctly installed:
+
+.. code-block:: bash
+
+   $ which pip
+
+Once again, if this isn't the pip in your python environment something went wrong.
+Now install fermipy by running:
+
+.. code-block:: bash
+
+   $ pip install dmsky
+
+To run the ipython notebook examples you will also need to install
+jupyter notebook:
+   
+.. code-block:: bash
+
+   $ pip install jupyter
+
+.. Running pip and setup.py with the ``user`` flag is recommended if you do not
+.. have write access to your python installation (for instance if you are
+.. running in a UNIX/Linux environment with a shared python
+.. installation).  To install fermipy into the common package directory
+.. of your python installation the ``user`` flag should be ommitted.
+
+Finally, check that dmsky imports:
+
+.. code-block:: bash
+
+   $ python
+   Python 2.7.8 (default, Aug 20 2015, 11:36:15)
+   [GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.56)] on darwin
+   Type "help", "copyright", "credits" or "license" for more information. 
+   >>> import dmsky
+   >>> dmsky.__file__
+
+
+The instructions describe how to install development versions of
+Fermipy.  Before installing a development version we recommend first
+installing a tagged release following the :ref:`pipinstall` 
+instructions above.
+
+The development version of Fermipy can be installed by running ``pip
+install`` with the URL of the git repository:
+
+.. code-block:: bash
+                
+   $ pip install git+https://github.com/fermiPy/dmsky.git
+
+This will install the most recent commit on the master branch.  Note
+that care should be taken when using development versions as
+features/APIs under active development may change in subsequent
+versions without notice.
+   
+   
+Upgrading
+---------
+
+By default installing fermipy with ``pip`` or ``conda`` will get the latest tagged
+released available on the `PyPi <https://pypi.python.org/pypi>`_
+package respository.  You can check your currently installed version
+of fermipy with ``pip show``:
+
+.. code-block:: bash
+
+   $ pip show fermipy
+
+or ``conda info``:
+
+.. code-block:: bash
+
+   $ conda info fermipy
+   
+To upgrade your fermipy installation to the latest version run the pip
+installation command with ``--upgrade --no-deps`` (remember to also
+include the ``--user`` option if you're running at SLAC):
+   
+.. code-block:: bash
+   
+   $ pip install fermipy --upgrade --no-deps
+   Collecting fermipy
+   Installing collected packages: fermipy
+     Found existing installation: fermipy 0.6.6
+       Uninstalling fermipy-0.6.6:
+         Successfully uninstalled fermipy-0.6.6
+   Successfully installed fermipy-0.6.7
+
+If you installed fermipy with ``conda`` the equivalent command is:
+
+.. code-block:: bash
+
+   $ conda update fermipy
+   
+   
+.. _gitinstall:
+   
+Developer Installation
+----------------------
+
+These instructions describe how to install fermipy from its git source
+code repository using the ``setup.py`` script.  Installing from source
+can be useful if you want to make your own modifications to the
+fermipy source code.  Note that non-developers are recommended to
+install a tagged release of fermipy following the :ref:`pipinstall` or
+instructions above.
+
+First clone the fermipy git repository and cd to the root directory of
+the repository:
+
+.. code-block:: bash
+
+   $ git clone https://github.com/fermiPy/fermipy.git
+   $ cd fermipy
+   
+To install the latest commit in the master branch run ``setup.py
+install`` from the root directory:
+
+.. code-block:: bash
+
+   # Install the latest commit
+   $ git checkout master
+   $ python setup.py install --user 
+
+A useful option if you are doing active code development is to install
+your working copy of the package.  This will create an installation in
+your python distribution that is linked to the copy of the code in
+your local repository.  This allows you to run with any local
+modifications without having to reinstall the package each time you
+make a change.  To install your working copy of fermipy run with the
+``develop`` argument:
+
+.. code-block:: bash
+
+   # Install a link to your source code installation
+   $ python setup.py develop --user 
+
+You can later remove the link to your working copy by running the same
+command with the ``--uninstall`` flag:
+
+.. code-block:: bash
+
+   # Install a link to your source code installation
+   $ python setup.py develop --user --uninstall
+   
+
+Specific release tags can be installed by running ``git checkout``
+before running the installation command:
+   
+.. code-block:: bash
+   
+   # Checkout a specific release tag
+   $ git checkout X.X.X 
+   $ python setup.py install --user 
+
+To see the list of available release tags run ``git tag``.
+   
+Issues
+------
+
+If you get an error about importing matplotlib (specifically something
+about the macosx backend) you might change your default backend to get
+it working.  The `customizing matplotlib page
+<http://matplotlib.org/users/customizing.html>`_ details the
+instructions to modify your default matplotlibrc file (you can pick
+GTK or WX as an alternative).  Specifically the ``TkAgg`` and
+``macosx`` backends currently do not work on OSX if you upgrade
+matplotlib to the version required by fermipy.  To get around this
+issue you can switch to the ``Agg`` backend at runtime before
+importing fermipy:
+
+.. code-block:: bash
+
+   >>> import matplotlib
+   >>> matplotlib.use('Agg')
+
+However note that this backend does not support interactive plotting.
+
+If you are running OSX El Capitan or newer you may see errors like the following:
+
+.. code-block:: bash
+                
+   dyld: Library not loaded
+
+In this case you will need to disable the System Integrity Protections
+(SIP).  See `here
+<http://www.macworld.com/article/2986118/security/how-to-modify-system-integrity-protection-in-el-capitan.html>`_
+for instructions on disabling SIP on your machine.
+
+In some cases the setup.py script will fail to properly install the
+fermipy package dependecies.  If installation fails you can try
+running a forced upgrade of these packages with ``pip install --upgrade``:
+
+.. code-block:: bash
+
+   $ pip install --upgrade --user numpy matplotlib scipy astropy pyyaml healpy wcsaxes ipython jupyter
