Outdated docs with regards to eslint

Created by: LukasWerfel

Hi there, I got a question regarding the docs.

In the section "Displaying Lint Output in the Editor" it says:

Then, add a file called .eslintrc to the project root

This does not seem to be the case anymore, since eslintConfig was added here.

If I understand correctly, that would mean that the docs are a bit outdated.

Since I am looking for my very first PR, I was wondering if I may open a PR (with some guidance) in order to fix this.
