server-env/server_environment/readme/DESCRIPTION.md

This module provides a way to define an environment in the main Odoo configuration file and to read some configurations from files depending on the configured environment: you define the environment in the main configuration file, and the values for the various possible environments are stored in the server_environment_files companion module.

The server_environment_files module is optional, the values can be set using an environment variable with a fallback on default values in the database.

The configuration read from the files are visible under the Configuration menu. If you are not in the 'dev' environment you will not be able to see the values contained in the defined secret keys (by default : 'passw', 'key', 'secret' and 'token').
