         Names of levels in MultiIndex.
 
+        This attribute provides access to the names of the levels in a `MultiIndex`.
+        The names are stored as a `FrozenList`, which is an immutable list-like
+        container. Each name corresponds to a level in the `MultiIndex`, and can be
+        used to identify or manipulate the levels individually.
