• Enhanced Documentation Links: Expanded documentation section with specific links to LLMD resources
• Footer: Added community engagement section with GitHub links and contribution calls-to-action

Notable Implementation Details

• Used HTML tables with width attributes for responsive multi-column layouts

• Maintained all original technical content while significantly improving presentation
• Preserved all links and references to existing documentation
