5. Click File | Save. 6. Create a Lightning app. Click File | New | Lightning Application. 7. Enter helloWorldApp for the name of the new app, and click OK. 8. This creates a helloWorldApp.app resource. 9. In the editor, enter the following markup for the app, which embeds the component you created in a Lightning app.
c:helloWorld refers to the component helloWorld.cmp using the default namespace c. If your organization has a registered namespace, you can use it to reference Lightning components, such asmyNamespace:helloWorld.

A .app resource can’t be included in Salesforce1 but a .cmp resource can. You can embed your components in a .app resource to preview it as a standalone app outside of Salesforce1.
