+`<paper-menu>` implements an accessible menu control with Material Design styling. The focused item
+is highlighted, and the selected item has bolded text.
+
+    <paper-menu>
+      <paper-item>Item 1</paper-item>
+      <paper-item>Item 2</paper-item>
+    </paper-menu>
+
+Make a multi-select menu with the `multi` attribute. Items in a multi-select menu can be deselected,
+and multiple item can be selected.
+
+    <paper-menu multi>
+      <paper-item>Item 1</paper-item>
+      <paper-item>Item 2</paper-item>
+    </paper-menu>
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-menu-background-color`   | Menu background color                                            | `--primary-background-color`
+`-paper-menu-color`               | Menu foreground color                                            | `--primary-text-color`
+`--paper-menu-disabled-color`     | Foreground color for a disabled item                             | `--disabled-text-color`
+`--paper-menu`                    | Mixin applied to the menu                                        | `{}`
+`--paper-menu-selected-item`      | Mixin applied to the selected item                               | `{}`
+`--paper-menu-focused-item`       | Mixin applied to the focused item                                | `{}`
+`--paper-menu-focused-item-after` | Mixin applied to the ::after pseudo-element for the focused item | `{}`
+
+### Accessibility
+
+`<paper-menu>` has `role="menu"` by default. A multi-select menu will also have
+`aria-multiselectable` set. It implements key bindings to navigate through the menu with the up and
+down arrow keys, esc to exit the menu, and enter to activate a menu item. Typing the first letter
+of a menu item will also focus it.
