 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`:
 
 ```js
+const anchor = require('markdown-it-anchor')

 module.exports = {
   markdown: {
     // options for markdown-it-anchor
