Fleshed out aliases section, loading the "redirect" keyword so that it's easier to find. Specifically added a "how aliases work" section. Added Discourse to comments section. Fleshed out themes/customizing, because it seems to be the source of a lot of questions on the forum.

As Hugo is a static site generator, the content produced is static and doesn’t interact with the users. The most common interaction people ask for is comment capability.
|
||
|
||
Hugo ships with support for [Disqus](https://disqus.com/), a third-party service that provides comment and community capabilities to website via JavaScript.
|
||
|
||
Your theme may already support Disqus, but even it if doesn’t, it is easy to add.
|
||
|
||
# Disqus Support
|
||
|
||
## Adding Disqus to a template
|
||
|
||
Hugo comes with all the code you would need to include load Disqus. Simply include the following line where you want your comments to appear:
|
||
|
||
{{ template "_internal/disqus.html" . }}
|
||
|
||
## Configuring Disqus
|
||
|
||
That template requires you to set a single value in your site config file, e.g. config.yaml.
|
||
|
||
disqusShortname = "XYW"
|
||
|
||
Additionally, you can optionally set the following in the front matter
|
||
for a given piece of content:
|
||
|
||
* **disqus_identifier**
|
||
* **disqus_title**
|
||
* **disqus_url**
|
||
|
||
## Conditional Loading of Disqus Comments
|
||
|
||
Users have noticed that enabling Disqus comments when running the Hugo web server on localhost causes the creation of unwanted discussions on the associated Disqus account. In order to prevent this, a slightly tweaked partial template is required. So, rather than using the built-in `"_internal/disqus.html"` template referenced above, create a template in your `partials` folder that looks like this:
|
||
|
||
```html
|
||
<div id="disqus_thread"></div>
|
||
<script type="text/javascript">
|
||
|
||
(function() {
|
||
// Don't ever inject Disqus on localhost--it creates unwanted
|
||
// discussions from 'localhost:1313' on your Disqus account...
|
||
if (window.location.hostname == "localhost")
|
||
return;
|
||
|
||
var dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = true;
|
||
var disqus_shortname = '{{ .Site.Params.disqusShortname }}';
|
||
dsq.src = '//' + disqus_shortname + '.disqus.com/embed.js';
|
||
(document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(dsq);
|
||
})();
|
||
</script>
|
||
<noscript>Please enable JavaScript to view the <a href="http://disqus.com/?ref_noscript">comments powered by Disqus.</a></noscript>
|
||
<a href="http://disqus.com/" class="dsq-brlink">comments powered by <span class="logo-disqus">Disqus</span></a>
|
||
```
|
||
|
||
Notice that there is a simple `if` statement that detects when you are running on localhost and skips the initialization of the Disqus comment injection.
|
||
|
||
Now, reference the partial template from your page template:
|
||
|
||
{{ partial "disqus.html" . }}
|
||
|
||
|
||
