 ([TL;DR](http://i.imgur.com/nH25yiH.png)) Gretel is a [Ruby on Rails](http://rubyonrails.org) plugin that makes it easy yet flexible to create breadcrumbs.
 It is based around the idea that breadcrumbs are a concern of the view, so you define a set of breadcrumbs in *config/breadcrumbs.rb* (or multiple files; see below) and specify in the view which breadcrumb to use.

 ## Building the breadcrumbs manually
 
 You can use the `breadcrumbs` method directly as an array. It will return an array with the breadcrumb links so you can build the breadcrumbs HTML manually:

 If you use this approach, you lose the built-in semantic breadcrumb functionality. One way to
 add them back is to use JSON-LD structured data:
 
 ```erb
 <script type="application/ld+json">
-  <%= breadcrumbs.structured_data(url_base: "https://example.com")) %>
+  <%= breadcrumbs.structured_data(url_base: "https://example.com") %>
 </script>
 ```
 
 Or, you can infer `url_base` from `request`:
 
 ```erb
 <script type="application/ld+json">
-  <%= breadcrumbs.structured_data(url_base: "#{request.protocol}#{request.host_with_port}")) %>
+  <%= breadcrumbs.structured_data(url_base: "#{request.protocol}#{request.host_with_port}") %>
 </script>

+### ARIA support
+
+You can improve the accessibility of your page with the markup that specified in [ARIA](https://www.w3.org/TR/wai-aria-practices/examples/breadcrumb/index.html). Gretel supports generating `aria-current` attribute:
+
+```erb
+<% breadcrumb :issue, @issue %>
+<%= breadcrumbs aria_current: "page" %>
+```
+
+This will generate the following HTML (indented for readability):
+
+```html
+<div class="breadcrumbs">
+  <a href="/">Home</a> &rsaquo;
+  <a href="/issues">All issues</a> &rsaquo;
+  <span class="current" aria-current="page">My Issue</span>
+</div>
 ```
