Release a new theme related to Grocery World http://market.ionic.io/themes/grocery-world. You can release theme for other ecommerce products also.
The Grocery World IONIC theme does not provide any backend support. It is just HTML and Sass based theme with proper angular directives and components. This theme allows the IONIC developer to integrate their REST API and the entire theme will be converted into a working app with their own data.
