Alright, just read it in depth.
The tutorial is just fine, its not exactly how I would have written it but not far from, not that my way of writing it would be the correct answer anyway. The only thing that annoys me is the grammatical errors, not typos but just structure-wise wrong. Not a big problem tho. It is easy to understand nonetheless.
Like I said, there is a couple of things I would have done differently. So perhaps I will use this as a base if I ever get the time to write one myself. I will of course credit you for it hehe.
I am looking forward to reading more from you
