+# Things to notice
+
+Take a look through the source and note:
+
+* The script tag that {@link guide.bootstrap bootstraps} the angular environment.
+* The text {@link angular.widget.HTML input widget} which is bound to the greeting name text.
+* No need for listener registration and event firing on change events.
+* The implicit presence of the `name` variable which is in the root {@link angular.scope scope}.
+* The double curly brace `{{markup}}`, which binds the name variable to the greeting text.
+* The concept of {@link guide.data-binding data binding}, which reflects any changes to the
+  input field in the greeting text.
