# Online Store 2.0: New reference theme available: Dawn

Dawn is Shopify’s first open source reference theme–built with performance and flexibility in mind, and using Online Store 2.0 features, including JSON templates, which support app blocks and sections on all pages.

Dawn uses a HTML-first, Javascript-only-as-needed approach to theme development, and can be used as a model for building new themes on Shopify. Using Shopify CLI, theme developers can [clone Dawn](https://shopify.dev/themes/tools/dawn) as a starting point for building new themes.
