How to decide when a resource/tutorial could be considered "oficial"

Hey there, I'm one of the maintainers of the React documentation in Spanish.

We're having a hard time deciding what courses/blog posts/videos/material we should add in our tutorials sections. We ( me, @carburo and @Darking360 ) wonder how can we decide whether a course could be considered as "official/blessed" so we can add it in the docs. How did you decide that an article is good enough to be included in the official documentation.

I know this is a really hard question to answer because this is a matter of taste, but any guidance here will be super helpful!

Thanks in advance!

Start by reviewing the React documentation's existing tutorials sections and the materials maintainers are considering, since the issue names no specific file or test. Done would be agreed guidance for deciding whether courses, blog posts, videos, or other resources are official enough to include.
