Add in the documentation what emotion is used for in the integration with Nextjs

• I have searched the issues of this repository and believe that this is not a duplicate.

Summary 💡

I’m implementing Material UI in Next.js v10 using the examples from the same Material UI repository, but I can’t understand the reason for using the emotion library, I know it’s to create a css cache, but why is this necessary? ?

In the documentation there is nothing about it and I think it should indicate why the use of emotion.

@mnajdova I get it! and of course there was a confusion with the versions of the documentation.

In the same way, the use of emotion is not very clear to me. Perhaps a couple of lines could be added to the Installation page commenting on why its use? Or a full page to document about this new integration in v5, because I couldn’t find it in the documentation.

And for those who come to the Next examples template, maybe indicate that emotion is not something for next but rather Material UI with a link to the documentation that I think it should have.

And finally thank you very much for the clarification 😁😁

Agreed. Our examples should be overly verbose with technical decisions. Whether this happens in the readme or code is not important to me.
