@j0eybrinkman I'm adding you to the contributors list for the project, and would really love for you to contribute more. Please consider that. We need more contributors! Thanks, Steve

@sspencerwire Thank you for the warm welcome. I will definitely continue to contribute more. I think I will start by re-writing the PHP and PHP-FPM guide for rocky 9 as I followed this guide while using a rocky 9 VPS to host a static website. (joeybrinkman.com) Anyways, thank you again and look forward to learning more about what I can do with Rocky through its docs and will try to help anyway I can along the way!

Thanks, Joey
