Hugo also ships with an internal template for [Disqus comments][disqus], a popular commenting system for both static and dynamic websites. In order to effectively use Disqus, you will need to secure a Disqus "shortname" by [signing up for the free service][disqussignup].
### Configure Disqus
To use Hugo's Disqus template, you first need to set a single value in your site's `config.toml` or `config.yml`:
Users have noticed that enabling Disqus comments when running the Hugo web server on `localhost` (i.e. via `hugo server`) causes the creation of unwanted discussions on the associated Disqus account.
You can create the following `layouts/partials/disqus.html`:
An internal template for the [Open Graph protocol](http://ogp.me/), metadata that enables a page to become a rich object in a social graph.
This format is used for Facebook and some other sites.
### Configure Open Graph
Hugo's Open Graph template is configured using a mix of configuration variables and [front-matter](/content-management/front-matter/) on individual pages.
{{<code-togglefile="config">}}
[params]
title = "My cool site"
images = ["site-feature-image.jpg"]
description = "Text about my cool site"
[taxonomies]
series = "series"
{{</code-toggle>}}
{{<code-togglefile="content/blog/my-post">}}
title = "Post title"
description = "Text about this post"
date = "2006-01-02"
images = ["post-cover.png"]
audio = []
video = []
series = []
tags = []
{{</code-toggle>}}
Hugo uses the page title and description for the title and description metadata.
The first 6 URLs from the `images` array are used for image metadata.
Various optional metadata can also be set:
- Date, published date, and last modified data are used to set the published time metadata if specified.
-`audio` and `video` are URL arrays like `images` for the audio and video metadata tags, respectively.
- The first 6 `tags` on the page are used for the tags metadata.
- The `series` taxonomy is used to specify related "see also" pages by placing them in the same series.
### Use the Open Graph Template
To add Open Graph metadata, include the following line between the `<head>` tags in your templates:
```
{{ template "_internal/opengraph.html" . }}
```
## Twitter Cards
An internal template for [Twitter Cards](https://developer.twitter.com/en/docs/tweets/optimize-with-cards/overview/abouts-cards),
metadata used to attach rich media to Tweets linking to your site.
### Configure Twitter Cards
Hugo's Twitter Card template is configured using a mix of configuration variables and [front-matter](/content-management/front-matter/) on individual pages.
{{<code-togglefile="config">}}
[params]
images = ["site-feature-image.jpg"]
description = "Text about my cool site"
{{</code-toggle>}}
{{<code-togglefile="content/blog/my-post">}}
title = "Post title"
description = "Text about this post"
images = ["post-cover.png"]
{{</code-toggle>}}
If `images` aren't specified in the page front-matter, then hugo searches for [image page resources](/content-management/image-processing/) with `feature`, `cover`, or `thumbnail` in their name.
If no image resources with those names are found, the images defined in the [site config](getting-started/configuration/) are used instead.
If no images are found at all, then an image-less Twitter `summary` card is used instead of `summary_large_image`.
Hugo uses the page title and description for the card's title and description fields. The page summary is used if no description is given.
### Use the Twitter Cards Template
To add Twitter card metadata, include the following line between the `<head>` tags in your templates:
