Hello @SEOSUK!

Thanks for the contribution!
I think you accidentally committed some README.md changes. If you revert commit c37fdc2, we can merge this PR.

Hi @ArisMorgens,

Thank you very much for pointing that out.
I’ve restored README.md to match the upstream master and updated the PR branch accordingly.
The README change was unintentional.

Thanks again for your review, and please let me know if any further adjustments are needed.
