When using Hugo with [GitHub Pages](http://pages.github.com/), you can provide your own template for a [custom 404 error page](https://help.github.com/articles/custom-404-pages/) by creating a 404.html template file in your `/layouts` folder. When Hugo generates your site, the `404.html` file will be placed in the root.
404 pages will have all the regular [page variables][pagevars] available to use in the templates.
In addition to the standard page variables, the 404 page has access to all site content accessible from `.Pages`.
```
▾ layouts/
404.html
```
## 404.html
This is a basic example of a 404.html template:
{{< code file="layouts/404.html" download="404.html" >}}
{{ define "main"}}
<main id="main">
<div>
<h1 id="title"><a href="{{ "/" | relURL }}">Go Home</a></h1>
</div>
</main>
{{ end }}
{{< /code >}}
## Automatic Loading
Your 404.html file can be set to load automatically when a visitor enters a mistaken URL path, dependent upon the web serving environment you are using. For example:
* [GitHub Pages](/hosting-and-deployment/hosting-on-github/). The 404 page is automatic.
* Apache. You can specify `ErrorDocument 404 /404.html` in an `.htaccess` file in the root of your site.
* Nginx. You might specify `error_page 404 /404.html;` in your `nginx.conf` file.
* Amazon AWS S3. When setting a bucket up for static web serving, you can specify the error file from within the S3 GUI.
* Amazon CloudFont. You can specify the page in the Error Pages section in the CloudFont Console. [Details here](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/custom-error-pages.html)
* Caddy Server. Using `errors { 404 /404.html }`. [Details here](https://caddyserver.com/docs/errors)
{{% note %}}
`hugo server` will not automatically load your custom `404.html` file, but you
can test the appearance of your custom "not found" page by navigating your
browser to `/404.html`.
