analyzing quantum algorithms which simulate fermionic systems.\nThis plugin library allows the electronic structure package `Psi4 \u003chttp://psicode.org\u003e`__ (licensed under GNU Lesser General Public License version 3) to interface with OpenFermion.\n\nInstallation\n------------\n\nTo start using OpenFermion-Psi4, first install `Psi4 \u003chttp://psicode.org\u003e`__.\nNote that Psi4 is designed specifically for the\n`Anaconda \u003chttps://www.anaconda.com/download\u003e`__ python distribution.\nWhile it is possible to install Psi4 without Anaconda, if one does use Anaconda python\nthe following commands will install Psi4 and pip (used to install OpenFermion-Psi4):\n\n.. code-block:: bash\n\n  conda config --add channels http://conda.anaconda.org/psi4\n  python -m conda install psi4\n  python -m conda install pip\n\nTo install the latest versions of OpenFermion and OpenFermion-Psi4 (in development mode):\n\n.. code-block:: bash\n\n  git clone https://github.com/quantumlib/OpenFermion-Psi4\n  cd OpenFermion-Psi4\n  python -m pip install -e .\n\nAlternatively, to install the latest PyPI releases as libraries (in user mode):\n\n.. code-block:: bash\n\n  python -m pip install --user openfermionpsi4\n\nAlso be sure to take a look at the `ipython notebook demo \u003chttps://github.com/quantumlib/OpenFermion-Psi4/blob/master/examples/openfermionpsi4_demo.ipynb\u003e`__.\n\nHow to contribute\n-----------------\n\nWe'd love to accept your contributions and patches to OpenFermion-Psi4.\nThere are a few guidelines you need to follow.\nContributions to OpenFermion-Psi4 must be accompanied by a Contributor License Agreement.\nYou (or your employer) retain the copyright to your contribution,\nthis simply gives us permission to use and redistribute your contributions as part of the project.\nHead over to https://cla.developers.google.com/\nto see your current agreements on file or to sign a new one.\n\nAll submissions, including submissions by project members, require review.\nWe use GitHub pull requests for this purpose. Consult\n`GitHub Help \u003chttps://help.github.com/articles/about-pull-requests/\u003e`__ for\nmore information on using pull requests.\nFurthermore, please make sure your new code comes with extensive tests!\nWe use automatic testing to make sure all pull requests pass tests and do not\ndecrease overall test coverage by too much. Make sure you adhere to our style\nguide. Just have a look at our code for clues. We mostly follow\n`PEP 8 \u003chttps://www.python.org/dev/peps/pep-0008/\u003e`_ and use\nthe corresponding `linter \u003chttps://pypi.python.org/pypi/pep8\u003e`_ to check for it.\nCode should always come with documentation.\n\nAuthors\n-------\n\n`Ryan Babbush \u003chttp://ryanbabbush.com\u003e`__ (Google),\n`Jarrod McClean \u003chttp://jarrodmcclean.com\u003e`__ (Google),\n`Kevin Sung \u003chttps://github.com/kevinsung\u003e`__ (University of Michigan),\n`Ian Kivlichan \u003chttp://aspuru.chem.harvard.edu/ian-kivlichan/\u003e`__ (Harvard),\n`Dave Bacon \u003chttps://github.com/dabacon\u003e`__ (Google),\n`Yudong Cao \u003chttps://github.com/yudongcao\u003e`__ (Harvard),\n`Chengyu Dai \u003chttps://github.com/jdaaph\u003e`__ (University of Michigan),\n`E.
