+*****************
+Deploying Blender
+*****************
+
+It is possible to deploy Blender in environments that are more
+restricted, use automation or have other special requirements.
+For example in an animation studio or for school courses.
+
+This page contains tips setting up Blender in such environments.
+
+Installing Blender
+==================
+
+Blender downloads can be extracted to any directory on the system, as
+a self contained installation. Multiple Blender versions can easily
+co-exist on the same system, and deployment can be automated using
+standard file management tools.
+
+New Blender versions may add, remove or changes functionality that
+change the results of production files. For a given project, it is
+advisable to use a single LTS (long term support) version of Blender.
+LTS versions receive bug fixes for two years.
+
+Working Offline
+===============
+
+For security or other reasons, workstation may not have internet access.
+
+By default Blender does not access the internet, however this can be
+enabled in the System preferences with the Online Access option.
+
+Working offline can be enforced by running with the ``--offline-mode``
+:ref:`command line argument <command-line-args-network-options>`.
+
+Bundling Extensions
+===================
+
+When working offline or in a more controlled environment, it may be useful
+to provide a set of extensions to all users. These can be served from a
+read-only system repository. This repository could exist on a network drive
+or in a system directory.
+
+The location of this system extension repository can be manually configured
+in the Extensions preferences.
+
+The ``$BLENDER_SYSTEM_REPOSITORY``
+:ref:`environment variable <command-line-args-environment-variables>`
+can also set the default location. This is a directory, within which a
+``system`` directory should exist. Each extension zip file should be
+extracted to its own folder, and which should then contain a
+``blender_manifest.toml`` file.
+
+Bundling Scripts
+================
+
+Besides extensions, it's possible to bundle scripts for presets,
+application templates, legacy add-ons, as well as scripts run on startup.
+
+Script directories can be manually added in the File Paths preferences.
+The ``$BLENDER_SYSTEM_SCRIPTS`` can also be used to add a script directory
+without modifying the preferences.
+
+These script directories are expected to contain specific directories
+like ``presets``, ``addons`` and ``startup`` for different types of
+scripts. See :ref:`blender-directory-path-layout` for a complete list.
+
+Startup Scripts
+---------------
+
+The Blender Python API can be used to customize Blender. This includes
+changing preferences, changing the startup file and adding UI elements.
+
+For example a ``startup/enable_addons.py`` script can be created to
+enable a set of add-ons for every user.
+
+.. code-block:: python
+
+   def register():
+       import addon_utils
+       addon_utils.enable("node_wrangler")
+
+   def unregister():
+       pass
+
+   if __name__ == "__main__":
+       register()
+
+VFX Platform
+============
+
+Blender follows the `VFX reference platform <https://vfxplatform.com>`_,
+which means it is able to run on the same systems as other VFX software
+and exchange image, volume and scene files with them.
+
+Python Version
+--------------
+
+Blender and the `by module <https://pypi.org/project/bpy/>`_ are only compatible
+with a single Python version. This makes it possible for add-ons and VFX software
+in general to only have to target a single Python version.
+
+Blender bundles a complete Python installation and does not interact with the
+system Python by default. This can be changed with the ``--python-use-system-env``
+:ref:`command line argument <command-line-args-python-options>`, if care is
+taken to set up a compatible Python version.
