+`paper-checkbox` is a button that can be either checked or unchecked.  User
+can tap the checkbox to check or uncheck it.  Usually you use checkboxes
+to allow user to select multiple options from a set.  If you have a single
+ON/OFF option, avoid using a single checkbox and use `paper-toggle-button`
+instead.
+
+Example:
+
+    <paper-checkbox></paper-checkbox>
+
+    <paper-checkbox checked></paper-checkbox>
+

+
+To change the ink color for checked state:
+
+    paper-checkbox::shadow #ink[checked] {

+To change the checkbox checked color:
+
+    paper-checkbox::shadow #checkbox.checked {
