I tried finding some videos to explain to my friends how the game works. They were either too brief and glossed over the important and interesting stuff, or they were too long and complex, too 'traditional' in the sense that they covered all the technical aspects of the game, but not the essence of the game.
Here, I try to explain the stuff that you just need to know to get you started - the rest you will learn along the way. I can easily go into more detail, but I tried to strike a balance between not enough and too much. Hopefully this helps! If you think more content like this would be good, let me know in the comments.
