+This module implements an event system (`Observer pattern`_) and is a
+base block for the Connector Framework. It can be used without
+using the full Connector though. It is built upon the ``component`` module.
+
+Documentation: http://odoo-connector.com/
+
+.. _Observer pattern: https://en.wikipedia.org/wiki/Observer_pattern

+
+Usage
+=====
+
+As a developer, you have access to a events system. You can find the
+documentation in the code or on http://odoo-connector.com
+
+In a nutshell, you can create trigger events::
+
+  class Base(models.AbstractModel):
+      _inherit = 'base'
+
+      @api.model
+      def create(self, vals):
+          record = super(Base, self).create(vals)
+          self._event('on_record_create').notify(record, fields=vals.keys())
+          return record
+
+And subscribe listeners to the events::
+
+  from odoo.addons.component.core import Component
+  from odoo.addons.component_event import skip_if
+
+  class MagentoListener(Component):
+      _name = 'magento.event.listener'
+      _inherit = 'base.connector.listener'
+
+      @skip_if(lambda self, record, **kwargs: self.no_connector_export(record))
+      def on_record_create(self, record, fields=None):
+          """ Called when a record is created """
+          record.with_delay().export_record(fields=fields)
+
+
+This module triggers 3 events:
+
+* ``on_record_create(record, fields=None)``
+* ``on_record_write(record, fields=None)``
+* ``on_record_unlink(record)``
+
