+
+CSV files without a header row
+------------------------------
+
+The first row of any CSV or TSV file is expected to contain the names of the columns in that file.
+
+If your file does not include this row, you can use the ``--no-headers`` option to specify that the tool should not use that fist row as headers.
+
+If you do this, the table will be created with column names called ``untitled_1`` and ``untitled_2`` and so on. You can then rename them using the ``sqlite-utils transform ... --rename`` command, see :ref:`cli_transform_table`.
