# Frontmatter Config

Frontmatter enables page based configuration. In every markdown file, you can use frontmatter config to override site-level or theme-level config options. Also, there are config options which you can only define in frontmatter.

Example usage:

```md
---
title: Docs with VitePress
editLink: true
---
```

You can access frontmatter data via the `$frontmatter` global in Vue expressions:

```md
{{ $frontmatter.title }}
```

## title

- Type: `string`

Title for the page. It's same as [config.title](/guides/guide-site-config#title), and it overrides the site-level config.

```yaml
---
title: VitePress
---
```

## titleTemplate

- Type: `string | boolean`

The suffix for the title. It's same as [config.titleTemplate](/guides/guide-site-config#titletemplate), and it overrides the site-level config.

```yaml
---
title: VitePress
titleTemplate: Vite & Vue powered static site generator
---
```

## description

- Type: `string`

Description for the page. It's same as [config.description](/guides/guide-site-config#description), and it overrides the site-level config.

```yaml

```

## head

- Type: `HeadConfig[]`

Specify extra head tags to be injected for the current page. They are [merged](/guides/guide-site-config#head) with the head tags injected by site-level config.

```yaml
---
head:
  - - meta
    - name: description
      content: hello
  - - meta
    - name: keywords
      content: super duper SEO
---
```

```ts
type HeadConfig =
  | [string, Record<string, string>]
  | [string, Record<string, string>, string]
```

## dir

- Type: `'ltr' | 'rtl' | 'auto'`

Overrides the [text direction](/guides/guide-site-config#dir) of the site for the current page.

```yaml

```

## Default Theme Only

The following frontmatter options are only applicable when using the default theme.

- `home` - Special layout for "Home Page". You may add extra options such as `hero` and `features` to rapidly create beautiful landing page.

```yaml
---
layout: doc

  /* page-specific styles */
}
```

### isHome
