+The sharing include is a sharing helper for a number of providers.
+Usage:
+  1) Include JB/sharing
+  2) Optionally assign the 'sharing_message_prefix' variable with a string
+  3) Optionally assign the 'sharing_context' variable with a context, where
+     "context" is a page object. Defaults to the current page if unset. See
+     "themes/tlvince/metabox.html" for an example.
+  Example:
+    <ul>
+        {% assign sharing_message_prefix = "Photo " %}
+        {% include JB/sharing %}
+    </ul>
 
-{% case site.JB.sharing.provider %}
-{% when "custom" %}
