+        The `copy` method provides a mechanism to create a duplicate of an
+        existing MultiIndex object. This is particularly useful in scenarios where
+        modifications are required on an index, but the original MultiIndex should
+        remain unchanged. By specifying the `deep` parameter, users can control
+        whether the copy should be a deep or shallow copy, providing flexibility
+        depending on the size and complexity of the MultiIndex.
 
         Parameters
         ----------
         names : sequence, optional
+            Names to set on the new MultiIndex object.
         deep : bool, default False
+            If False, the new object will be a shallow copy. If True, a deep copy
+            will be attempted. Deep copying can be potentially expensive for large
+            MultiIndex objects.
         name : Label
             Kept for compatibility with 1-dimensional Index. Should not be used.
 
         Returns
         -------
         MultiIndex
+            A new MultiIndex object with the specified modifications.
