+JSON Logging
+============
+
+This addon allows to output the Odoo logs in JSON.
+
+Configuration
+-------------
+
+The json logging is activated with the environment variable
+``ODOO_LOGGING_JSON`` set to ``1``.
+
+In order to have the logs from the start of the server, you should add
+``logging_json`` in the ``--load`` flag or in the ``server_wide_modules``
+option in the configuration file.
