 paper-toolbar
 ============
+
+`paper-toolbar` is a horizontal bar containing items that can be used for
+label, navigation, search and actions.  The items place 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 title>Title</div>
+  <paper-icon-button icon="more" 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 title class="middle">Middle Title</div>
+  <div title class="bottom">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.
