After over a decade running on the same design, the Centmin Mod website has been rebuilt from the ground up. The old site served us well, but it was showing its age - hard to read on phones, no dark mode, and documentation scattered across forum threads instead of being front and center on the site itself.

The new site fixes all of that. Every page now works properly on mobile, tablet, and desktop. There's a dark mode that follows your system preference or can be toggled manually. And most importantly, the documentation has been massively expanded with dedicated pages covering every major Centmin Mod feature in detail.

Here's what's new:

• Over 50 documentation pages covering Nginx, PHP-FPM, MariaDB, SSL, firewalls, email, backups, and more
• A comprehensive Menu Option 21 Data Management guide for backups, migrations, and S3 transfers
• Improved installation instructions with step-by-step walkthroughs for AlmaLinux and Rocky Linux
• An AI-powered search (press Cmd+K or click the search bar) that actually understands what you're looking for
• An AI chatbot assistant that can answer technical questions about Centmin Mod configuration and troubleshooting
• This live news feed you're reading right now, which automatically pulls the latest announcements from the community forums

The community forums remain the best place for support, bug reports, and discussions. The site and forums work together - the site provides the documentation and guides, while the forums handle the conversations and troubleshooting that need back-and-forth discussion.

If you spot any issues with the new site or have suggestions, feel free to post in the feedback and suggestions forum.
