+------------------------------------------
+
+It is possible -- although not recommended -- to pass custom configuration
+options to yamllint with the ``-d`` (short for ``--config-data``) option.
+
+Its content can either be the name of a pre-defined conf (example: ``default``
+or ``relaxed``) or a serialized YAML object describing the configuration.
