 To use your own custom weather files for a specific location, this can be done in **one** of two ways:
 
-- Rename the filename references in your local `options_lookup.tsv <https://github.com/NREL/resstock/blob/master/resources/options_lookup.tsv>`_ in the ``resources`` folder to match your custom weather file names. For example, in the options_lookup tsv, the Location ``AL_Birmingham.Muni.AP.722280`` is matched to the ``weather_file_name=USA_AL_Birmingham.Muni.AP.722280.epw``. To update the weather file for this location, the `weather_file_name` field needs to be updated to match your new name specified.
