Codexual here, I've setup time codes related to the video when to run the commands ( https://www.youtube.com/watch?v=NtSd4IPjpLQ ), hopefully that would help. Speaking of help, depending if I like your demeanor I might help you if you are stuck... But most of the time I am too lazy to care and or just want to avoid people 'coz I am anti-social. So GOOD LUCK :D
