 # Static resources
 
 We often want to ship a website with a static resource, such as an image, icon, CSS, or JavaScript file.
-For this, we need to register static resources.
+For CSS and JavaScript files, we can use the resource registry to register, then deliver, them to the client browser.
+
+The resource registry provides a programmatic way, either in code or through the web, to extend and configure the dependencies between static resources.
+It also automatically manages caching of static resources.
+If you were to hard-code these resources in templates with `<link>` or `<script>` tags, you would not have these advantages.
