Video doesn't work. Make sure when you post a youtube link that you do it like this.
Take the link and delete he part that says "https:youtu.be/", you don't need that part, just the letters and numbers after it. Then put it between this [YOUTUBE.][/YOUTUBE.] without the periods.
As for the video in all honesty you were WAY to far zoomed in, don't do that from now on. You need to capture the whole picture in the screen.
