TIL: I'm impressed with Next.js that you can do this with a few lines In next.config.js

@icyJoseph I don't think that works

curl -H -L "Accept: text/markdown" https://react.dev/reference/react

returns the HTML

[icyJoseph]

@rickhanlonii mmm let me take a stab at it again

Edit: I think the command should've been:

curl -L -H "Accept: text/markdown" https://react.dev/reference/react

That being said, in the live site I still see HTML too. Locally this returns markdown:

curl -L -H "Accept: text/markdown" http://localhost:3000/reference/react

Has this been promoted to a production release?
