+**1. Middleware** — intercepts markdown requests and rewrites to the API route:
+
+```ts
+// middleware.ts
+import { createMarkdownMiddleware } from 'next-markdown-mirror/pages';
+export default createMarkdownMiddleware();
+export const config = { matcher: ['/((?!_next/static|_next/image|favicon.ico).*)'] };

+**2. API route handler** — fetches your HTML internally and converts to Markdown:
+
+```ts
+// pages/api/md-mirror/[...path].ts
+import { createPagesMarkdownHandler } from 'next-markdown-mirror/pages';
+
+export default createPagesMarkdownHandler({
+  baseUrl: process.env.NEXT_PUBLIC_SITE_URL!,
