 This shield can only be used with a board that provides a mikroBUS |trade|
 socket and defines a ``mikrobus_i2c`` node label for the mikroBUS |trade| I2C
+interface or a ``mikrobus_spi`` node label for the mikroBUS |trade| SPI
 interface (see :ref:`shields` for more details).
 
+.. note::
+
+   By default the Weather Click is configured to use the I2C interface. In
+   order to use the SPI interface the jumper settings must be changned. See
+   the `Weather Click Schematic`_ for further details.
