+``ioda``
+========
+
+The ``uw`` mode for configuring and running the IODA components of the JEDI framework.
+
+.. literalinclude:: ioda/help.cmd
+   :language: text
+   :emphasize-lines: 1
+.. literalinclude:: ioda/help.out
+   :language: text
+
+All tasks take the same arguments. For example:
+
+.. literalinclude:: ioda/run-help.cmd
+   :language: text
+   :emphasize-lines: 1
+.. literalinclude:: ioda/run-help.out
+   :language: text
+
+Examples
+^^^^^^^^
+
+The examples use a configuration file named ``config.yaml`` with contents similar to:
+
+.. highlight:: yaml
+.. literalinclude:: /shared/ioda.yaml
+
+Its contents are described in section :ref:`ioda_yaml`.
+
+* Run ``ioda`` on an interactive node
+
+   .. code-block:: text
+
+      $ uw ioda run --config-file config.yaml --cycle 2024-05-22T12
+
+The driver creates a ``runscript.ioda`` file in the directory specified by ``run_dir:`` in the config and runs it, executing ``ioda``.
+
+* Run ``ioda`` via a batch job
+
+   .. code-block:: text
+
+      $ uw ioda run --config-file config.yaml --cycle 2024-05-22T12 --batch
+
+The driver creates a ``runscript.ioda`` file in the directory specified by ``run_dir:`` in the config and submits it to the batch system. Running with ``--batch`` requires a correctly configured ``platform:`` block in ``config.yaml``, as well as appropriate settings in the ``execution:`` block under ``ioda:``.
+
+* Specifying the ``--dry-run`` flag results in the driver logging messages about actions it would have taken, without actually taking any.
+
+  .. code-block:: text
+
+     $ uw ioda run --config-file config.yaml --cycle 2024-05-22T12 --batch --dry-run
+
+.. include:: /shared/key_path.rst

+
+Supports ``base_file:`` and ``update_values:`` blocks (see :ref:`updating_values` for details).
