the tutorial does not bring something interesting to the world of open source, apart from that, I would recommend fixing the following points:
1) A good tutorial It has a structure (Requirements, body of the tutorial, small summary of what you are going to learn, curriculum, etc.).
2) Try, as far as possible, generate structured paragraphs, a good tutorial has it.
3) The tutorial that you presented, from my point of view, is good, but it does not contain enough content to be approved.

Although I am not a moderator, I hope you take my valuable advice and put it into practice. good day
