 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

+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 keys named '*passw*'.

+Default values
+--------------
+
+When using the ``server.env.mixin`` mixin, for each env-computed field, a
+companion field ``<field>_env_default`` is created. This field is not
+environment-dependent. It's a fallback value used when no key is set in
+configuration files / environment variable.
+
+When the default field is used, the field is made editable on Odoo.
+
+Note: a present key with an empty value do not fallback on the default field.

 Usage
 =====
 
-To use this module, in your code, you can follow this example::
+You can include a mixin in your model and configure the env-computed fields
+by an override of ``_server_env_fields``.
 
-    from openerp.addons.server_environment import serv_config
-    for key, value in serv_config.items('external_service.ftp'):
-       print (key, value)
+::
 
-    serv_config.get('external_service.ftp', 'tls')
