The fastest path to a fully dual-marked site is the Astro integration.

<Steps>

<Step>

## Install

<Tabs items={["bun", "npm", "yarn"]}>
<Tab value="bun">
```bash
bun add @dualmark/astro @dualmark/core @dualmark/converters
```
</Tab>
<Tab value="npm">
```bash
npm install @dualmark/astro @dualmark/core @dualmark/converters
```
</Tab>
<Tab value="yarn">
```bash
yarn add @dualmark/astro @dualmark/core @dualmark/converters
```
</Tab>
</Tabs>

</Step>

<Step>

## Configure

Add Dualmark to your Astro config.

```js title="astro.config.mjs"
import { defineConfig } from "astro/config";
import dualmark from "@dualmark/astro";

export default defineConfig({
  site: "https://example.com",
  integrations: [
    dualmark({
      siteUrl: "https://example.com",
      collections: {
        blog: { converter: "blog" },
      },
      llmsTxt: { enabled: true },
    }),
  ],
});
```

</Step>

<Step>

## Build

```bash
bun run build
```

Every blog post now has a markdown twin at `/blog/<slug>.md`, an `llms.txt` is auto-generated, and an Astro middleware injects the `Link: <...>; rel="alternate"; type="text/markdown"` header on every HTML response.

</Step>

<Step>

## Verify

```bash
bun run dev
# in another terminal:
npx @dualmark/cli verify http://localhost:4321/blog/your-post
```

Expect `Score 80/80` (or higher with full negotiation).
