Where do I submit feedback on the documentation? I've found a slight problem

Reading some stuff I have found a slight problem with wording....
(Maybe I am being petty. I can't say.)

I would just like to ask where is the best place to mention it?

Which documentation?

The website (and pretty much anything else) is all on GitHub so if you think there is a problem raise a pull request to fix it

For some node-red documentation.

I was reading it and there is a slight typo (missing word).
