+# iron-autogrow-textarea
+
+`iron-autogrow-textarea` is an element containing a textarea that grows in height as more
+lines of input are entered. Unless an explicit height or the `maxRows` property is set, it will
+never scroll.
+
+Example:
+
+    <iron-autogrow-textarea id="a1">
+      <textarea id="t1"></textarea>
+    </iron-autogrow-textarea>
+
+Because the `textarea`'s `value` property is not observable, you should use
+this element's `bind-value` instead for imperative updates. Alternatively, if
+you do set the `textarea`'s `value` imperatively, you must also call `update`
+to notify this element the value has changed.
+
+    Example:
+        /* preferred, using the example HTML above*/
+        a1.bindValue = 'some\ntext';
+
+        /* alternatively, */
+        t1.value = 'some\ntext';
+        a1.update();
