-Adding Custom Packages
-======================
-
-If you wish to make additional Python modules available to use with
-extensions that you have developed, use the following information.
-
-Prerequisite
-------------
-
-|RCC| manages the |RCE| environment using Supervisor. To add custom packages
-you need to install your instance of |RCE| as a self managed
-instance. This will let you to update the ``PYTHONPATH`` without |RCC|
-overwriting it. You can then extend the ``PYTHONPATH`` to find packaged
-outside of the |RCC| managed environment. To install |RCE| as a self-managed
-service using |RCC|, see the
-:ref:`Self-managed Instructions <control:set-self-managed-supervisor>`.
-
-Adding Custom Packages
-----------------------
-
-Once you have your instance configured as self-managed, use the following steps.
-
-1. Add the modules to the |RCE| instance directory,
-   :file:`/home/{user}/.rccontrol/{instance-id}`.
-2. Add this location to your ``PYTHONPATH`` environment variable. This is set
-   in the :file:`/home/{user}/.rccontrol/supervisor/supervisor.ini` file. For
-   more information about ``PYTHONPATH``, see the `PYTHONPATH documentation`_.
-
-.. code-block:: ini
-
-   [program:enterprise-1_script]
-   numprocs = 1
-   redirect_stderr = true
-   environment = PYTHONPATH="",GIT_SSL_CAINFO="/home/user/.rccontrol-profile/etc/ca-bundle.crt"
-
-3. Specify the hook for your added module on the
-   :menuselection:`Admin --> Settings --> Hooks` page. For
-   example, ``python:rcextensions/you.custom.hook``
-4. Restart |RCE| using the ``rccontrol restart <instance-id>`` command.
-   For more information, see the :ref:`RhodeCode Control CLI <control:rcc-cli>`
-   documentation.

-Nix Packaging
-=============
-
-|RCE| is installed using |Nix Package Manager|. The Nix environment provides
-the following features for maintenance and deployment:
-
-* Atomic upgrades and rollbacks
-* Complete dependency management
-* Garbage collection
-* Binary patching
-* Secure channel updates
-* Nix works on Windows, Linux, and OSX
-
-The complete list of dependencies can be found in
-:file:`/opt/rhodecode/store/{unique-hash}`.
-
-.. note::
-
-   No |RCE| data is stored in this location.
-   
-.. warning::
-
-   Never alter any of the packages in the store. Always use the
-   :ref:`RhodeCode Control CLI <control:rcc-cli>` update functions to keep
-   the packages and instances updated.
