+### Multiple blogs
+
+By default, the classic theme assumes only one blog per website and hence includes only one instance of the blog plugin. If you would like to have multiple blogs on a single website, it's possible too! You can add another blog by specifying another blog plugin in the `plugins` option for `docusaurus.config.js`.
+
+Set the `routeBasePath` to the URL route that you want your second blog to be accessed on. Note that the `routeBasePath` here has to be different from the first blog or else there could be a collision of paths! Also, set `path` to the path to the directory containing your second blog's entries.
+
+```js title="docusaurus.config.js"
+module.exports = {
+  // ...
+  plugins: [
+    [
+      '@docusaurus/plugin-content-blog',
+      {
+        /**
+         * URL route for the blog section of your site.
+         * *DO NOT* include a trailing slash.
+         */
+        routeBasePath: 'my-second-blog',
+        /**
+         * Path to data on filesystem relative to site dir.
+         */
+        path: './my-second-blog',
+      },
