Im happy to hear that you were able to get things working. Learning a new language usually involve trial-and-error, but I promise it's worth it. The documentation is a good place to start. I'd also recommend reading articles from popular sources like Kotlin Academy, watching experts code on the Kotlin YouTube channel, and joining the Kotlin slack (it's far more active than the subreddit). https://kotlinlang.org/docs/home.html https://kt.academy/article link to this video
