+The production deployment for gvapgsql is performed using saltstack and consists
+of the following steps:
+
+* installation of native dependencies

+.. index:: installation
+
+=======
+Install
+=======
+
+Working Environment
+===================
+
+You have several options in setting up your working environment.  We recommend
+using virtualenv to separate the dependencies of your project from your
+system's python environment.  If on Linux or Mac OS X, you can also use
+virtualenvwrapper to help manage multiple virtualenvs across different
+projects.
+
+.. index:: virtualenv
+
+Virtualenv Only
+---------------
+
+First, make sure you are using `virtualenv`_. Once that's installed, create
+your virtualenv:
+
+.. code-block:: sh
+
+    $ virtualenv --distribute gvapgsql
+
+.. _virtualenv: https://virtualenv.pypa.io/en/latest/
+
+You will also need to ensure that the virtualenv has the project directory
+added to the path.
+
+.. index:: virtualenvwrapper
+
+Virtualenv with virtualenvwrapper
+------------------------------------
+
+In Linux and Mac OSX, you can install `virtualenvwrapper
+<http://virtualenvwrapper.readthedocs.org/en/latest/>`_, which will take care
+of managing your virtual environments and adding the project path to the
+`site-directory` for you:
+
+.. code-block:: sh
+
+    $ mkdir gvapgsql
+    $ mkvirtualenv -a gvapgsql gvapgsql-dev
+    $ cd gvapgsql && add2virtualenv `pwd`
+
+
+.. index:: pip, requirements, dependencies
+
+Installation of Dependencies
+=============================
+
+Depending on where you are installing dependencies:
+
+In development:
+
+.. code-block:: sh
+
+    $ pip install -r requirements/local.txt
+
+For production:
+
+.. code-block:: sh
+
+    $ pip install -r requirements.txt
+
+.. index:: celery, worker, file queue
+
+Running the Celery worker
+=========================
+
+gvapgsql uses the `Celery`_ distributed task queue system. The gvapgsql logic is
+executed by a celery worker. After all dependencies are installed you can go
+into the gvapgsql directory and run the celery worker with:
+
+.. code-block:: sh
+
+    $ cd gvapgsql
+    $ celery -A gvapgsql worker -Q pgsql -l info
+
+.. _Celery: http://www.celeryproject.org/
