+
+Both `absURL` and `relURL` consider the configured value of `baseURL` in your site's [`config` file][configuration]. Given a `baseURL` set to `https://example.com/hugo/`:
+
+```
+{{ "mystyle.css" | absURL }} → "https://example.com/hugo/mystyle.css"
+{{ "mystyle.css" | relURL }} → "/hugo/mystyle.css"
+{{ "http://gohugo.io/" | relURL }} →  "http://gohugo.io/"
+{{ "http://gohugo.io/" | absURL }} →  "http://gohugo.io/"
+```
+
+The last two examples may look strange but can be very useful. For example, the following shows how to use `absURL` in [JSON-LD structured data for SEO][jsonld] where some of your images for a piece of content may or may not be hosted locally:
+
+{{< code file="layouts/partials/schemaorg-metadata.html" download="schemaorg-metadata.html" >}}
+<script type="application/ld+json">
+{
+    "@context" : "http://schema.org",
+    "@type" : "BlogPosting",
+    "image" : {{ apply .Params.images "absURL" "." }}
+}
+</script>
+{{< /code >}}
+
+The above uses the [apply function][] and also exposes how the Go template parser JSON-encodes objects inside `<script>` tags. See [the safeJS template function][safejs] for examples of how to tell Hugo not to escape strings inside of such tags.
+
+{{% note "Ending Slash" %}}
+`absURL` and `relURL` are smart about missing slashes, but they will *not* add a closing slash to a URL if it is not present.
