+Simplified transformation
+************
+
+A simplified version can be used to transform data without the need for a configuration file. The simplified version can be run directly from the command line.
+
+For example, to transform data from AIR Cede to OED, the following command can be used:
+
+.. code-block:: bash
+
+    ods_tools transform --format air-oed --input-file input.csv --output-file output.csv
+
+
+The command will run the transformation using the default configuration for the specified formats (to select a specific version, a specific batch size for large transformations, or a database connection a configuration file will be necessary).
+Currently supported formats are: air-oed, oed-air.
