-    %(name)s standard deviation
+    Calculate %(name)s standard deviation.
+
+    Normalized by N-1 by default. This can be changed using the `ddof`
+    argument.
 
     Parameters
     ----------
     ddof : int, default 1
         Delta Degrees of Freedom.  The divisor used in calculations
-        is ``N - ddof``, where ``N`` represents the number of elements.""")
+        is ``N - ddof``, where ``N`` represents the number of elements.
+    *args, **kwargs
+        For NumPy compatibility. No additional arguments are used.
+
+    Returns
+    -------
+    Series or DataFrame
+        Returns the same object type as the caller of the %(name)s calculation.
+
+    See Also
+    --------

+    numpy.std : Equivalent method for Numpy array
+
+    Notes
+    -----
+    The default `ddof` of 1 used in Series.std is different than the default
+    `ddof` of 0 in numpy.std.
+
+    A minimum of one period is required for the rolling calculation.
