# Metadata
The [Metadata][1] extension makes it possible to add metadata to a document
which gives more control over the theme in a page-specific context.
[1]: https://python-markdown.github.io/extensions/meta_data/
## Installation
Add the following lines to your `mkdocs.yml`:
``` yaml
markdown_extensions:
- meta
```
## Usage
Metadata is written as a series of key-value pairs at the beginning of the
Markdown document, delimited by a blank line which ends the metadata context.
Naturally, the metadata is stripped from the document before rendering the
actual page content and made available to the theme.
Example:
``` markdown
title: Lorem ipsum dolor sit amet
description: Nullam urna elit, malesuada eget finibus ut, ac tortor.
path: path/to/file
source: file.js
# Headline
...
```
See the next section which covers the metadata that is supported by Material.
### Setting a hero text
Material exposes a simple text-only page-local hero via Metadata, as you can
see on the current page when you scroll to the top. It's as simple as:
``` markdown
hero: Metadata enables hero teaser texts
```
### Linking sources
When a document is related to a specific set of source files and the `repo_url`
is defined inside the project's `mkdocs.yml`, the files can be linked using the
`source` key:
``` markdown
source: file.js
```
The filename is appended to the `repo_url` set in your `mkdocs.yml`, but can
be prefixed with a `path` to ensure correct path resolving:
Example:
``` markdown
path: tree/master/docs/extensions
source: metadata.md
```
Result:
See the [source][2] section for the resulting output.
[2]: #__source
### Redirecting to another page
It's sometimes necessary to move documents around in the navigation tree and
redirect user from the old URL to the new one. The `redirect` meta-tag allows
to create a redirection from the current document to the address specified in
the tag.
For instance, if your document contains:
``` markdown
redirect: /new/url
```
accessing that document's URL will automatically redirect to `/new/url`.
### Overrides
#### Page title
The page title can be overridden on a per-document level:
``` markdown
title: Lorem ipsum dolor sit amet
```
This will set the `title` tag inside the document `head` for the current page
to the provided value. It will also override the default behavior of Material
for MkDocs which appends the site title using a dash as a separator to the page
title.
#### Page description
The page description can also be overridden on a per-document level:
``` yaml
description: Nullam urna elit, malesuada eget finibus ut, ac tortor.
```
This will set the `meta` tag containing the site description inside the
document `head` for the current page to the provided value.
#### Disqus
As describe in the [getting started guide][3], the Disqus comments section can
be enabled on a per-document level:
``` markdown
disqus: your-shortname
```
Disqus can be disabled for a specific page by setting it to an empty value:
``` markdown
disqus:
```
