 Flatten Tool for BODS
 +++++++++++++++++++++
 
+BODS 0.4
+========
+
+Flatten tool can be used to flatten and unflatten BODS 0.4 data.
+
+Flatten tool has not yet been updated to handle the BODS 0.4 schema. (For the moment the ``--schema`` option should not be used when handling BODS 0.4 data.) This documentation will be updated when the work is complete.

+
 flatten and unflatten
+---------------------
+
+This data standard has a list as the root element,
+as opposed to other standards where the root element is a dict with meta data and a list of data.
+When flattening and unflattening, use the ``--root-is-list`` option.
+
+The id element is ``statementId``, so also use the ``--id-name`` option.

 Order is important
