{% include linkrefs.html %} 

Because this theme is built on Bootstrap, you can simply use a specific attribute on an element to insert a tooltip. 

Suppose you have a glossary.yml file inside your \_data folder. You could pull in that glossary definition like this:

{% raw %} 
```html
<a href="#" data-toggle="tooltip" data-original-title="{{site.data.glossary.jekyll_platform}}">Jekyll</a> is my favorite tool for building websites.</a>
```
{% endraw %}

This renders to the following:

<a href="#" data-toggle="tooltip" data-original-title="{{site.data.glossary.jekyll_platform}}">Jekyll</a> is my favorite tool for building websites.</a>
