Hi @ademidun,

Thanks for submitting your article as a suggested addition to the list.

Unfortunately this doesn't currently meet the level of what I'd deem a high quality article that belongs on the list for the following reasons:

• The site this is published on is confusing (it shows Save, Unpublish buttons for readers, there's a random markdown section in the way of reading the actual article)
• Broken/missing links, leftover todo comments:
  •  "If you want more context, watch the video tutorial that I made to accompany this tutorial [todo]"
  • "You can see in this commit [TODO]"
• Various spelling mistakes that haven’t been corrected:
  • "tuorial"
  • "visble"

Overall my biggest question is why does this article merit being added rather than the original one from Nader that this is largely based on, especially if Nader's article is added at a later point? You mention that "This tutorial will focus mainly on parts that are different from Nader’s tutorial instead of going over every single line of code.”, but it's not clear why this is valuable or what is significantly different.

I'm happy to assess a resubmission at a later point once the quality of the article is appropriate, and I get a sense that this adds significant value to readers that they wouldn't get from Nader's original article.
