   • Select Extensions → Manage, and then the Upload Package File tab.
   • Click the 'Browse' button and select the downloaded zip file from step 1.
   • Click Upload & Install.
   • Check that the component installed properly.

• Check that the items can now be displayed by using URL 'localhost/index.php?option=com_helloworld&id=1' , '...&id=2', etc.
