hello how are you, I hope you are well, I am very interested in your project, I have seen all the issues that you have there all these issues dominated except the last question that is the difference between mysql and postgres because I have not handled much mysql. I have not done a tutorial before but for what I would like to know how much of each topic you want to get to, because if you need it urgently, you can not expand each topic very simply so that the user who will use this tutorial goes hand in hand . for the topics that you have planned this tutorial is aimed at beginners. tell me what time you have planned to make this tutorial?
