“Its a remake of the 2016 video tutorials on YouTube. I had a close look at all the viewers questions that were posted in the YouTube comments so that I can anticipate possible hurdles and explain them better in the new videos. And I straightened some parts and included new ideas and updates. Its based on Org 9.3 which was the current version this summer.”
