I Need A Full Tutorial On How To Master Next js

I need documentation on how to master Next.js from zero to hero.

Why am I asking this with all the YouTube tutorials?

Well, the tutorials don't explain everything needed to write a full website that is ready to be deployed and used.

I come from React.js as I think I've reached a point where I did a good job learning a good amount of it, and I know what to look for when I need help, like for caching I use react-query. But here in Next.js every tutorial I watch or docs I read, they just explain a specific thing, for example, if they are explaining something and they come across something else, they just say that they have a full course on 'this'. Please guys is there a full tutorial to be able to comfortably write a full app and deploy it with all the good practices?

Free is always better
