         Parameters
         ----------
-        xr_args, xr_kwargs are passed directly to the underlying xarray function.
-        The following are added by cf_xarray:
-
         positive_upward: optional, bool
             Change sign of the derivative based on the ``"positive"`` attribute of ``coord``
             so that positive values indicate increasing upward.
             If ``positive=="down"``, then multiplied by -1.
