+## Image Lazy Loading
+
+You can enable lazy loading for each image tag in the content via config:
+
+```js
+// image lazy loading is disabled by default
+export default {
+  markdown: {
+    lazyLoading: true
+  }
+}
+```
+
 ## Advanced Configuration
 
 VitePress uses [markdown-it](https://github.com/markdown-it/markdown-it) as the Markdown renderer. A lot of the extensions above are implemented via custom plugins. You can further customize the `markdown-it` instance using the `markdown` option in `.vitepress/config.js`:
