+# The NativeLink documentation
+
+This is the NativeLink documentation hosted at <https://docs.nativelink.com>.
+
+## 📚 Stack
+
+The NativeLink documentation uses a custom, highly efficient, high performance
+stack. Getting a bunch of bleeding-edge tools to work well together can be
+challenging. Feel free to copy-paste it into your own projects.
+
+- [Diátaxis](https://diataxis.fr/) as overarching documentation philosophy.
+- [Pnpm](https://github.com/pnpm/pnpm) as production bundler.
+- [Bun](https://github.com/oven-sh/bun) as build-time TypeScript interpreter.
+- [Biome](https://biomejs.dev/) as linting toolchain.
+- [Astro](https://astro.build/) as meta-framework.
+- [Starlight](https://starlight.astro.build/de/) as documentation framework.
+- [Qwik](https://qwik.dev/) as SSR component framework.
+- [TailwindCSS 4.0-alpha](https://tailwindcss.com/blog/tailwindcss-v4-alpha) for
+  component styling which makes use of [LightningCSS](https://lightningcss.dev/)
+  for faster CSS processing.
+- [Cloudflare Pages/Workers](https://pages.cloudflare.com/) for deployments.
+
+## 🚀 Common workflows
+
+See `package.json` for build scripts.
+
+This project requires `pnpm`. The nix flake ships a compatible version.
+
+```bash
+# Install dependencies with pnpm. Don't install with bun.
+pnpm install
+
+# Run a development server. Doesn't rebuild the autogenerated parts of the docs.
+pnpm dev
+
+# Run formatter and linter checks.
+pnpm check
+
+# Apply formatter and linter fixes.
+pnpm fix
+
+# Test cloudflare deployments locally. Useful when debugging SSR. Rebuilds the
+# autogenerated parts of the docs.
+pnpm preview
+```
+
+When deploying to Cloudflare, make sure to set the `PNPM_VERSION` to `8.15.5` to
+stay in sync with the flake. Also, use `pnpm exec playwright install && pnpm
+build` on the Cloudflare worker. This sets up headless Chromium which is used to
+generate mermaid diagrams during the build. You don't need to set playwright up
+locally as it's already configured in the flake.
+
+## 🐛 Known issues
+
+- `"@builder.io/qwik": "=1.5.6"` because `1.5.7` is bugged.
+- We use Bun as internal TypeScript processor, but can't use it as bundler yet.
+- HTML comments aren't correctly removed from Markdown documents.
+- The changelog needs to be excluded from `pagefind`.
+- `"@playform/compress": "=0.0.12"` because `0.0.13` doesn't properly compress
+  CSS.
