+iron-localstorage
+=================
+
+Element access to localStorage.  The "name" property
+is the key to the data ("value" property) stored in localStorage.
+
+`iron-localstorage` automatically saves the value to localStorage when
+value is changed.  Note that if value is an object auto-save will be
+triggered only when value is a different instance.
+
+```html
+<iron-localstorage name="my-app-storage" value="{{value}}"></iron-localstorage>
+```
