# 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

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: <shortname>
```

This will insert a comment system on _every page, except the index page_.

## Customization

### Selective integration

If the [Metadata][5] 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"

    ``` yaml
    ---
    disqus: <shortname>
    ---

    ...
    ```

=== "Disable Disqus"

    ``` yaml
    ---
    disqus: ""
    ---

    ...
    ```

### Other comment systems

In order to integrate another JavaScript-based comment system provider, you can
[extend the theme][7] and [override the `disqus` block][8]:

``` html
{% block disqus %}
  <!-- Add custom comment system integration here -->
{% endblock %}
```
