# Advanced Configuration

VuePress uses 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 .vuepress/config.js:

module.exports = {
  markdown: {
    // options for markdown-it-anchor
    anchor: { permalink: false },
    // options for markdown-it-toc
    toc: { includeLevel: [1, 2] },
    config: md => {
      // use more markdown-it plugins!
      md.use(require('markdown-it-xxx'))
    }
  }
}
