I agree, to add on to make the tutorial better you have to think all the possible ways to promote your tutorial like you are selling it so think of these questions when remaking the tutorial if you wish to do better:
-
What is special about my tutorial that makes it stand out compared to the other tutorials already available?
-
Who is my intended audience for the tutorial? Is the tutorial comprehensive for the intended audience?
There’s a lot more if you truly want to make a great tutorial that will help the community out but these are some to get started with.
Edit: Sorry suspicious is a word with negative and dangerous connotation @Xx_FROSTBITExX, I would like to apologize for my accusations.
Currently, your tutorial will need to directly compete with the one made by the Venomous Owl on youtube which seems to have the most views so far on the topic if you want to make a great DevForum tutorial.
Edit: It’s not bad though, but as others have mentioned you will have to add more value to the tutorial such as including good coding practices and explaining why to do so, which you edit your post:
If you do so then you will eventually make a way better and more comprehensive tutorial that will benefit everyone.
