Show HN: CarbonSheets – Host your own customizable cheatsheet portal In GitHub

Hi HN, I built CarbonSheets over the weekend.. a simple and free cheatsheet portal where you can host and share your documentation and cheatsheets directly in your own GitHub repository with minimal setup. Key Features: Self-hosted content: Keep your cheatsheets in your own Git repos. Developer UX: Built-in keyboard shortcuts, customizable view modes, and a distraction-free Zen mode. Rich Formatting & Tools: Powered by a flexible JSON schema with an in-app editor and schema validator. Support mermaid JS, Syntax highlighting, callouts, results section etc. Exporting: Export cheatsheets directly to PNG or PDF. Links: Live App: carbonsheets.vercel.app Instructions and Clone-able GitHub Repo to host your own: github.com/elnoxvie/carbonsheet (opinion) I'd love to hear your thoughts on the app!
