+wis2box can derive station information from `OSCAR/Surface`_.  To verify station metadata from OSCAR/Surface:
+
+.. code-block:: bash
+
+   wis2box metadata station get WSI
+
+
+where ``WSI`` is the WIGOS Station Identifier.  This command will return the information required in the
+station list for wis2box data processing and publication.  To add the station information to the station list,
+copy and paste the output of the above command, or rerun the above command, writing to the station list
+automatically:
+
+
+.. code-block:: bash
+
+   wis2box metadata station get WSI >> ~/wis2box-data/metadata/station/station_list.csv

    The ``station_list.csv`` requires column names ``station_name`` and the ``wigos_station_identifier`` (WSI) with which the station is registered in `OSCAR`_.  Optionally, you can provide a ``traditional_station_identifier (TSI)`` column.
    The TSI can be left empty if your data contains a WSI. If your data contains a TSI but no WSI, the ``station_list.csv`` will be used to derive the corresponding WSI for that station.
