+
+        The ``aggregate`` method enables flexible and efficient aggregation of grouped
+        data using a variety of functions, including built-in, user-defined, and
+        optimized JIT-compiled functions.
+
+        Parameters
+        ----------
+        func : function, str, list, dict or None
+            Function to use for aggregating the data. If a function, must either
+            work when passed a Series or when passed to Series.apply.
+
+            Accepted combinations are:
+
+            - function
+            - string function name
+            - list of functions and/or function names, e.g. ``[np.sum, 'mean']``
+            - None, in which case ``**kwargs`` are used with Named Aggregation. Here
+              the output has one column for each element in ``**kwargs``. The name of
+              the column is keyword, whereas the value determines the aggregation
+              used to compute the values in the column.
+
+              Can also accept a Numba JIT function with
+              ``engine='numba'`` specified. Only passing a single function is supported
+              with this engine.
+
+              If the ``'numba'`` engine is chosen, the function must be
+              a user defined function with ``values`` and ``index`` as the
+              first and second arguments respectively in the function signature.
+              Each group's index will be passed to the user defined function
+              and optionally available for use.
+
+            .. deprecated:: 2.1.0
+
+                Passing a dictionary is deprecated and will raise in a future version
+                of pandas. Pass a list of aggregations instead.
+        *args
+            Positional arguments to pass to func.
+        engine : str, default None
+            * ``'cython'`` : Runs the function through C-extensions from cython.
+            * ``'numba'`` : Runs the function through JIT compiled code from numba.
+            * ``None`` : Defaults to ``'cython'`` or globally setting
+                ``compute.use_numba``
+
+        engine_kwargs : dict, default None
+            * For ``'cython'`` engine, there are no accepted ``engine_kwargs``
+            * For ``'numba'`` engine, the engine can accept ``nopython``, ``nogil``
+              and ``parallel`` dictionary keys. The values must either be ``True`` or
+              ``False``. The default ``engine_kwargs`` for the ``'numba'`` engine is
+              ``{'nopython': True, 'nogil': False, 'parallel': False}`` and will be
+              applied to the function
+
+        **kwargs
+            * If ``func`` is None, ``**kwargs`` are used to define the output names and
+              aggregations via Named Aggregation. See ``func`` entry.
+            * Otherwise, keyword arguments to be passed into func.
+
+        Returns
+        -------
+        Series
+            Aggregated Series based on the grouping and the applied aggregation
+            functions.
+
+        See Also
+        --------
+        SeriesGroupBy.apply : Apply function func group-wise
+            and combine the results together.
+        SeriesGroupBy.transform : Transforms the Series on each group
+            based on the given function.
+        Series.aggregate : Aggregate using one or more operations.
+
+        Notes
+        -----
+        When using ``engine='numba'``, there will be no "fall back" behavior internally.
+        The group data and group index will be passed as numpy arrays to the JITed
+        user defined function, and no alternative execution attempts will be tried.
+
+        Functions that mutate the passed object can produce unexpected
+        behavior or errors and are not supported. See :ref:`gotchas.udf-mutation`
+        for more details.
