+   :description lang=en: Hosting Docusaurus sites on Read the Docs.
+
+`Docusaurus`_ is a static-site generator that builds a single-page application with fast client-side navigation and out-of-the-box documentation features.
+
+Minimal configuration required to build a Docusaurus project on Read the Docs looks like this,
+specifying a nodejs toolchain on Ubuntu, using multiple :ref:`build <config-file/v2:build>` commands to install the requirements,
+build the site, and copy the output to $READTHEDOCS_OUTPUT:
+
+.. code-block:: yaml
+   :caption: .readthedocs.yaml
+
+    version: 2
+    build:
+    os: "ubuntu-22.04"
+    tools:
+        nodejs: "18"
+    commands:
+        # "docs/" was created following the Docusaurus tutorial:
+        # npx create-docusaurus@latest docs classic
+        # but you can just use your existing Docusaurus site
+        #
+        # Install Docusaurus 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 --recursive docs/build/* $READTHEDOCS_OUTPUT/html/

+Quick start
+-----------

+- If you have an existing Docusaurus project you want to host on Read the Docs, check out our :doc:`/intro/add-project` guide.

+
+Configuring Docusaurus and Read the Docs addons
+-----------------------------------------------
+
+For optimal integration with Read the Docs, make the optional following configuration changes to your Docusaurus config.
+
+.. contents::
+   :depth: 1
+   :local:
+   :backlinks: none
+
+Set the canonical URL
+~~~~~~~~~~~~~~~~~~~~~
+
+A :doc:`canonical URL </canonical-urls>` allows you to specify the preferred version of a web page
+to prevent duplicated content.
+
+Set your Docusaurus `url`_  to your Read the Docs canonical URL using `dotenv <https://www.npmjs.com/package/dotenv>`__ and a
+:doc:`Read the Docs environment variable </reference/environment-variables>`:
+
+.. code-block:: js
+    :caption: docusaurus.config.js
+
+    import 'dotenv/config';
+
+    export default {
+        url: process.env.READTHEDOCS_CANONICAL_URL,
