6. Click Finish.
   The new ZF2 project is created, and displayed in the PHP Explorer represented by a Zend Framework icon

The generated project includes a Zend Framework 2 application skeleton with pre-configured dependencies and there is therefore no need to take any additional actions (e.g., running Composer) before actually running the project in a browser.

To deploy your application:

1. Open the 'deployment.xml' file (opened and displayed by default with project creation).
2. In the Testing area, click Launch application.
   The Launch PHP Application dialog is displayed.
3. Verify the deployment URL, and click Finish.
   Your project is deployed to the remote Zend Server and launched in Zend Studio.
