# Adding a comment system
Material for MkDocs is natively integrated with [Disqus][1], a comment system
that provides a wide range of features like social integrations, user profiles,
as well as spam and moderation tools. Of course, other comment systems can be
integrated, too.

## Configuration
### Disqus

:octicons-milestone-24: Default: _none_
First, ensure you've set [`site_url`][3] in `mkdocs.yml`. Then, to integrate
Material for MkDocs with [Disqus][1], create an account and a site giving you a
[shortname][4], and add it to `mkdocs.yml`:
``` yaml
extra:
disqus:
```
This will insert a comment system on _every page, except the index page_.

### Metadata
The [Metadata][5] extension, which is part of the standard Markdown library,
adds the ability to add [front matter][6] to a document and can be enabled via
`mkdocs.yml`:
``` yaml
markdown_extensions:
- meta
```
Front matter is written as a series of key-value pairs at the beginning of the
Markdown document, delimited by a blank line which ends the YAML context.

## Customization
### Selective integration

:octicons-mortar-board-24: Difficulty: _easy_
If the [Metadata][7] extension is enabled, you can disable or enable Disqus for
specific pages by adding the following to the front matter of a page:
=== "Enable Disqus"
``` markdown
---
disqus:
---
```
=== "Disable Disqus"
``` markdown
---
disqus: ""
---
```

### Other comment systems
[:octicons-file-code-24: Source][8] ·
:octicons-mortar-board-24: Difficulty: _easy_
In order to integrate another JavaScript-based comment system provider, you can
[extend the theme][9] and [override the `disqus` block][10]:
``` html
{% block disqus %}
{% endblock %}
```
