+This module extends the functionality of Accounting Odoo module, to
+auto generate fiscal years.
+
+Once installed, a cron is running each day. It will create, for each company,
+a new fiscal year, if it is the last day of the current fiscal year.
+
+This module is interesting specially in multi company context, to avoid annoying setup every year.
+
+The fiscal year created has a classical "12 monthes" duration, but the accountant
+can modify it, once created.
+
+Exemple
+~~~~~~~
+
+If a company has it last fiscal year, defined as:
+
+- ``name``: FY 2021-2022
+- ``date_from``: 2021-06-01
+- ``date_to``: 2022-05-31
+
+When the cron will be executed on May 31, 2022, it will create the following fiscal year:
+
+- ``name``: FY 2022-2023
+- ``date_from``: 2022-06-01
+- ``date_to``: 2023-05-31
