Within setup-guide.md, I’d like to be able to get the absolute URL of some of the supporting files so I can provide sample download code like this:

```sh
wget {{< ref "app.conf" >}} -O app.conf
```

But ref isn’t suitable for this task because app.conf isn’t a page. I imagine the answer is simple but I haven’t been able to find a way to do this yet. How do I get the absolute URL of a page resource?

That is part of the story.

That said, there isn’t a built-in shortcode to get the reference to a resource, but it’s fairly simple to create one, e.g:

{{ $resource := .Page.Resources.Get ($.Get 0) }}
{{ with $resource }}
{{ $resource.Permalink }}
{{ end }}

The above is typed from memory, but probably correct …

OK, my memory is fading … Try

{{ $resource := .Page.Resources.GetMatch ($.Get 0) }}
{{ with $resource }}
{{ $resource.Permalink }}
{{ end }}

With that change and the following in my content file:

```sh
wget {{< resource-ref "docker-compose.yml" >}} -O docker-compose.yml
```

I get:

wget 

 -O docker-compose.yml

Obviously it’s getting a blank string now. Any idea what’s wrong here?

Rename setup-guide.md to index.md

content/
└── post/
    └── setup-guide/
        ├── index.md
        ├── app.conf
        ├── docker-compose.yml
        └── sample_config.yml

Page resources only exist with bundles, either leaf or branch.
