Strapi v4 Docs Is Bad?

Now when I search about anything in the internet about strapi it shows the v3 solutions which isn’t useful for me because it’s completely different from the v4 solutions and the docs is so bad like when I want to create custom controller or custom server files I don’t find anything in the docs any suggetions?

Agreed. The docs aren’t robust for V4. I opened a ticket on this same topic. Unfortunately support wasn’t helpful either. I think the V4 release is a bit premature.
