+Material design: [Toolbars](https://www.google.com/design/spec/components/toolbars.html)
+
+`paper-toolbar` is a horizontal bar containing items that can be used for
+label, navigation, search and actions.  The items placed inside the
+`paper-toolbar` are projected into a `class="horizontal center layout"` container inside of
+`paper-toolbar`'s Shadow DOM.  You can use flex attributes to control the items'
+sizing.
+
+Example:
+
+```html
+<paper-toolbar>
+  <paper-icon-button icon="menu" on-tap="menuAction"></paper-icon-button>
+  <div class="title">Title</div>
+  <paper-icon-button icon="more-vert" on-tap="moreAction"></paper-icon-button>
+</paper-toolbar>
+```
+
+`paper-toolbar` has a standard height, but can made be taller by setting `tall`
+class on the `paper-toolbar`.  This will make the toolbar 3x the normal height.
+
+```html
+<paper-toolbar class="tall">
+  <paper-icon-button icon="menu"></paper-icon-button>
+</paper-toolbar>
+```
+
+Apply `medium-tall` class to make the toolbar medium tall.  This will make the
+toolbar 2x the normal height.
+
+```html
+<paper-toolbar class="medium-tall">
+  <paper-icon-button icon="menu"></paper-icon-button>
+</paper-toolbar>
+```
+
+When `tall`, items can pin to either the top (default), middle or bottom.  Use
+`middle` class for middle content and `bottom` class for bottom content.
+
+```html
+<paper-toolbar class="tall">
+  <paper-icon-button icon="menu"></paper-icon-button>
+  <div class="middle title">Middle Title</div>
+  <div class="bottom title">Bottom Title</div>
+</paper-toolbar>
+```
+
+For `medium-tall` toolbar, the middle and bottom contents overlap and are
+pinned to the bottom.  But `middleJustify` and `bottomJustify` attributes are
+still honored separately.
+
+To make an element completely fit at the bottom of the toolbar, use `fit` along
+with `bottom`.
+
+```html
+<paper-toolbar class="tall">
+  <div id="progressBar" class="bottom fit"></div>
+</paper-toolbar>
+```
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-toolbar-title`      | Mixin applied to the title of the toolbar | `{}`
+`--paper-toolbar-background` | Toolbar background color     | `--default-primary-color`
+`--paper-toolbar-color`      | Toolbar foreground color     | `--text-primary-color`
+`--paper-toolbar-height`     | Custom height for toolbar    | `64px`
+`--paper-toolbar-sm-height`  | Custom height for small screen toolbar | `56px`
+`--paper-toolbar`            | Mixin applied to the toolbar | `{}`
+`--paper-toolbar-content`    | Mixin applied to the content section of the toolbar | `{}`
+`--paper-toolbar-medium`     | Mixin applied to medium height toolbar | `{}`
+`--paper-toolbar-tall`       | Mixin applied to tall height toolbar | `{}`
+
+### Accessibility
+
+`<paper-toolbar>` has `role="toolbar"` by default. Any elements with the class `title` will
+be used as the label of the toolbar via `aria-labelledby`.
