Kotlin course in a new dimension

This is a course on the Kotlin programming language. Recently, Google officially added Kotlin as an Android development language. However, there is still a lack of Kotlin translations or materials for learning Kotlin in Korea. However, if you go to kotlinlang.org, the content on Kotlin is well organized, although it is in English. So, I studied kotlinlang.org myself and organized the content into a video. I think it will be helpful to other people studying Kotlin, so I organized the material.
