Hey Yassin 👋 this is a great initiative and I'd love to see such a guide that makes it easier for the community to build their own generators!!
However, there's a major caveat to this. The DMMF is an undocumented API that's not considered part of the official API surface and might break unexpectedly with any release, so it's very intentionally not documented in our own resources (somewhat related context also in this issue: #10725).
I would still love to see such a guide, do you maybe have a personal blog where you could publish it? Otherwise, platforms like Hashnode or dev.to are great to publish blog posts without the need of setting up your own blog. While we are not able to include such a guide in our own resources, I do think we can link to it from the Community generators-section in our docs!
