+======================================
+Server Environment Ir Config Parameter
+======================================
+
+Override System Parameters from server environment file.
+Before using this module, you must be familiar with the
+server_environment module.
+
+Installation
+============
+
+There is no specific installation instruction for this module.
+
+Configuration
+=============
+
+To configure this module, you need to add a section ``[ir.config_parameter]`` to
+you server_environment_files configurations, where the keys are the same
+as would normally be set in the Systems Parameter Odoo menu.
+
+When first using a value, the system will read it from the configuration file
+and override any value that would be present in the database, so the configuration
+file has precedence.
+
+When creating or modifying values that are in the configuration file, the
+module replace changes, enforcing the configuration value.
+
+For example you can use this module in combination with web_environment_ribbon:
+
+.. code::
+
+   [ir.config_parameter]
+   ribbon.name=DEV
+
+.. image:: https://odoo-community.org/website/image/ir.attachment/5784_f2813bd/datas
+   :alt: Try me on Runbot
+   :target: https://runbot.odoo-community.org/runbot/149/9.0
+
+Known issues / Roadmap
+======================
+
+* When the user modifies System Parameters that are defined in the config
+  file, the changes are ignored. It would be nice to display which system
+  parameters come from the config file and possibly make their key and value
+  readonly in the user interface.
+
+Bug Tracker

+Bugs are tracked on `GitHub Issues
+<https://github.com/OCA/server-tools/issues>`_. In case of trouble, please
+check there if your issue has already been reported. If you spotted it first,
