Template Details
This project is an Astro Starlight theme that aims to bring a Starlight site close to VitePress in both visuals and layout. It places the sidebar, body content and table of contents in one centred column, with the table of contents sitting next to the content rather than drifting to the far edge of the screen on wide displays. The theme uses the Inter typeface. The repository follows a pnpm workspace structure: packages/i-cant-believe-its-not-vitepress is the theme itself, and docs/ is a demo site that uses the theme. During development the theme is pulled in through a workspace link, so changes to the theme package are reflected immediately in the demo site when running pnpm dev. Installation instructions, configurable options and the theme's internal structure are documented in the theme package's README. The project is MIT licensed, currently has very few stars, and is a small theme released by an individual.

How this score is calculated
Our heuristic uses license records (up to 30), a demo link (12), a preview (10), stars (15), recorded maintenance (15), description completeness (8), feature records (5) and classification data (5). It is not a code, security or performance test, or a Google score. A link does not establish tested functionality.

A demo link is listed. Check it with your own content and viewport sizes; its presence does not confirm that forms, authentication or payments work.
The catalog identifies Astro as the primary stack. Check the actual dependency manifest and lockfile for versions and hosting requirements. These notes use recorded metadata, not a code audit or a deployment test.

Source file / repository# I Can't Believe It's Not VitePress A [Starlight](https://starlight.astro.build) theme that looks and lays out like [VitePress](https://vitepress.dev) — one centred band, Inter, and a table of contents that stays next to the words it describes instead of drifting to the far edge of a wide monitor. ``` packages/i-cant-believe-its-not-vitepress/ the theme docs/ a demo site that uses it ``` ## Develop ```sh pnpm install pnpm dev # demo site at localhost:4321 pnpm build ``` The theme is consumed by the demo through a workspace link, so edits to `packages/i-cant-believe-its-not-vitepress` show up in `pnpm dev` immediately. See [the package README](packages/i-cant-believe-its-not-vitepress/README.md) for installation, options and how the theme is put together. ## License MIT
