 The first argument is a ``description`` and the second is the ``location`` of the external link or local resource file.
 The optional argument ``copy_file=True`` (default value of ``False``) will copy a local file into the output directory.
 The optional argument ``resource_license`` can be used to define a data license for an additional resource.
 The ``resource_license`` is in the form of a dictionary with mandatory string ``name`` and ``url`` values, and an optional ``description``.
 The optional argument ``file_type="HistFactory"`` (default value of ``None``) can be used to identify statistical models provided in the HistFactory JSON
 format rather than relying on certain trigger words in the ``description`` (see `pyhf section of submission documentation`_).
+The optional argument ``file_type="ProSelecta"`` (default value of ``None``) can be used to identify C++ snippets in the ProSelecta format for use with
+the NUISANCE framework for event generators in neutrino physics (see `NUISANCE section of submission documentation`_).
 
 **Please note:** The default license applied to all data uploaded to HEPData is `CC0`_. You do not
 need to specify a license for a resource file unless it differs from `CC0`_.
