• Updated Readme to reflect the same.

Fyi, I think the lint tests, etc only run when someone's raising a PR for the non-first time. In other words, new contributors do not have the workflow run for them unless you approve it. From the results I see the lints are broken for a lot of files, so I suppose that's the reason these weren't detected earlier.

Anyway, I guess I could raise another PR after this to fix the linting errors for all the broken files if you'd like.

Thanks for the PR!

That would be fantastic! I created an issue for the linter failing tests #65
