 Toasts are lightweight notifications designed to mimic the push notifications that have been popularized by mobile and desktop operating systems. They're built with flexbox, so they're easy to align and position.
 
+## Overview
+
+Things to know when using the toast plugin:
+
+- If you're building our JavaScript from source, it [requires `util.js`]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/javascript/#util).
+- Toast are opt-in for performance reasons, so **you must initialize them yourself**.
+- Toast will auto hide if you do not specify `autohide: false`
+
+Got all that? Great, let's see how they work with some examples.
+
 ## Examples
 
 A basic toast can include a header (though it doesn't strictly need one) with whatever contents you like. The header is also `display: flex`, so `.mr-auto` and `.ml-auto` can be used for easy pushing of content, as well as all our flexbox utilities.

+## JavaScript behavior
+
+### Usage
+
+Initialize toasts via JavaScript:
+
+{% highlight js %}
+$('.toast').toast(option)
+{% endhighlight %}
+
+### Options
+
+Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-animation=""`.

+<table class="table table-bordered table-striped">
+  <thead>
+    <tr>
+      <th style="width: 100px;">Name</th>
+      <th style="width: 100px;">Type</th>
+      <th style="width: 50px;">Default</th>
+      <th>Description</th>

+        <p>If a number is supplied, delay is applied to both hide/show</p>

+
+### Methods
+
+{% include callout-danger-async-methods.md %}
+
+#### `$().toast(options)`
+
+Attaches a toast handler to an element collection.
+
+#### `.toast('show')`
+
+Reveals an element's toast. **Returns to the caller before the toast has actually been shown** (i.e. before the `shown.bs.toast` event occurs).
+You have to manually call this method, instead your toast won't show.
+
+{% highlight js %}$('#element').toast('show'){% endhighlight %}
+
+#### `.toast('hide')`
+
+Hides an element's toast. **Returns to the caller before the toast has actually been hidden** (i.e. before the `hidden.bs.toast` event occurs). You have to manually call this method if you made `autohide` to `false`.
+
+{% highlight js %}$('#element').toast('hide'){% endhighlight %}
+
+#### `.toast('dispose')`
+
+Hides an element's toast. Your toast will remain on the DOM but won't show anymore.
+
+{% highlight js %}$('#element').toast('dispose'){% endhighlight %}
+
+### Events
