Hello Choi Il-ju, It's a shame, but thank you for leaving a review.

It would be nice if there was a tutorial on how to use it in Airflow~

Hello Choi Il-ju, Airflow has its own other lectures. If I were to put Airlfow lectures here, I would have to put them back from the basics, but I think it would confuse students, so I think I need to think about it. If you could change the review to something positive, I will think about it positively.. haha
