+        """
+        Compute covariance with Series, excluding missing values.
+
+        The two `Series` objects are not required to be the same length and
+        will be aligned internally before the covariance is calculated.
+
+        Parameters
+        ----------
+        other : Series
+            Series with which to compute the covariance.
+        min_periods : int, optional
+            Minimum number of observations needed to have a valid result.
+        ddof : int, default 1
+            Delta degrees of freedom.  The divisor used in calculations
+            is ``N - ddof``, where ``N`` represents the number of elements.
+
+        Returns
+        -------
+        float
+            Covariance between Series and other normalized by N-1
+            (unbiased estimator).
