+   :description lang=en: Hosting Markdoc documentation on Read the Docs.
+
+`Markdoc`_ is a powerful documentation framework that allows you to write documentation in a flavor of Markdown.
+
+Minimal configuration is required to build an existing Markdoc project on Read the Docs.
+
+.. code-block:: yaml
+   :caption: .readthedocs.yaml
+
+    version: 2
+
+    build:
+        os: ubuntu-24.04
+        tools:
+            nodejs: "22"
+        commands:
+            # Install dependencies
+            - cd docs/ && npm install
+            # Build the site
+            - cd docs/ && npm run build
+            # Copy generated files into Read the Docs directory
+            - mkdir --parents $READTHEDOCS_OUTPUT/html/
+            - cp --verbose --recursive docs/out/* $READTHEDOCS_OUTPUT/html/
+
+.. _Markdoc: https://markdoc.io/
+
+Example configuration
+---------------------
+
+In order to build a Markdoc project on Read the Docs,
+you need to generate static HTML from the Next JS build:
+
+.. code-block:: js
+   :caption: next.config.js
+
+    const withMarkdoc = require('@markdoc/next.js');
+
+    const nextConfig = {
+        // Optional: Export HTML files instead of a Node.js server
+        output: 'export',
+
+        // Optional: Change links `/me` -> `/me/` and emit `/me.html` -> `/me/index.html`
+        trailingSlash: true,
+
+        // Use the proper base path for prod and PR builds.
+        basePath: process.env.READTHEDOCS_CANONICAL_URL || '',```
+    }
+
+    module.exports =
+        withMarkdoc({mode: 'static'})({
+            pageExtensions: ['js', 'jsx', 'ts', 'tsx', 'md', 'mdoc'],
+            ...nextConfig,
+    });
