Configuration

Without any configuration, the page is pretty minimal, and the user has no way to navigate around the site. To customize your site, let's first create a .vitepress directory inside your docs directory. This is where all VitePress-specific files will be placed. Your project structure is probably like this:

.
├─ docs
│  ├─ .vitepress
│  │  └─ config.js
│  └─ index.md
└─ package.json

The essential file for configuring a VitePress site is .vitepress/config.js, which should export a JavaScript object:

export default {
  title: 'VitePress',
  description: 'Just playing around.'
}

In the above example, the site will have the title of VitePress, and Just playing around. as the description meta tag.
