+Setup and Teardown
+~~~~~~~~~~~~~~~~~~
+
+In data workflows it's common to create resources (such as a compute
resource), use it to do some work, and then tear it down. Airflow provides the
concept of setup and teardown tasks to support this need.
+
+Features of setup and teardown tasks:
+
+ * If you clear a task, its setups and teardowns will be cleared.
+ * By default, teardown tasks are ignored for the purpose of evaluating dag
run state.
+ * A teardown task will run if it's setup was successful, even if its work
tasks failed.
+ * Teardown tasks are ignore when setting dependencies against task groups.
