+DAG testing
+===========
+
+To ease and speed up process of developing DAGs you can use ``InProcessExecutor`` - a single
+process executor for debugging purposes. Using this executor you can run and debug DAGs
+from your IDE.
+
+**IDE setup steps:**
+
+1. Add ``main`` block at the end of your DAG file to make it runnable:
+
+  .. code-block:: python
+
+    if __name__ == '__main__':
+      dag.clear(reset_dag_runs=True)
+      dag.run()
 
 Review comment:
   Isn't there already a `dag.cli()` or something?
