+@taskgroup decorator
+--------------------
+
+TaskGroup can be created using @taskgroup decorator, it takes one mandatory
argument 'group_id' which is same as constructor of TaskGroup class. It works
exactly same as creating TaskGroup using context manager 'with
TaskGroup('groupid') as section:'.
+
+.. code-block:: python
+
+ @task
+ def task_1(value):
+ return f'[ Task1 {value} ]'

+
+ @task
+ def task_2(value):
+ print( f'[ Task2 {value} ]')
+
+
+ @taskgroup(group_id='section_1')
+ def section_1(value):
+ return task_2(task_1(value))
