+======================================
+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.
+
+The user cannot write, create, or delete System Parameters that are defined in the
+configuration files.
+
+For example you can use this module in combination with web_environment_ribbon:
+
+.. code::
+
+   [ir.config_parameter]
+   ribbon.name=DEV
