+===================

+
+The development server provided by the Django ecosystem may be fine for a testing environment or small contained setups. However special consideration must be given when deploying InvenTree in a real-world environment.
+
+Django apps provide multiple deployment methods - see the `Django documentation <https://docs.djangoproject.com/en/2.2/howto/deployment/>`_.
+
+There are also numerous online tutorials describing how to deploy a Django application either locally or on an online platform.
+
+Following is a simple tutorial on serving InvenTree using `Gunicorn <https://gunicorn.org/>`_. Gunicorn is a Python WSGI server which provides a multi-worker server which is much better suited to handling multiple simultaneous requests. 
+
+Install Gunicorn
+----------------
+
+Gunicorn can be installed using PIP:
+
+`pip3 install gunicorn`
+
+
+Configure Static Directories
+----------------------------
+
+Directories for storing *media* files and *static* files should be specified in the ``config.yaml`` configuration file. These directories are the ``MEDIA_ROOT`` and ``STATIC_ROOT`` paths required by the Django app.
+
+Collect Static Files
+--------------------
+
+The required static files must be collected into the specified ``STATIC_ROOT`` directory. Run ``python3 manage.py collectstatic``
+
+Configure Gunicorn
+------------------
+
+The Gunicorn server can be configured with a simple configuration file (e.g. python script). An example configuration file is provided in ``InvenTree/gunicorn.conf.py``
+
+.. literalinclude :: ../InvenTree/gunicorn.conf.py
+   :language: python
+   :linenos:
+
+This file can be used to configure the Gunicorn server to match particular requirements.
+
+Run Gunicorn
+------------
+
+From the directory where ``manage.py`` is located:
+
+Run ``gunicorn -c gunicorn.conf.py InvenTree.wsgi``
