The WooCommerce Blocks Handbook provides documentation for designers and developers on how to extend or contribute to blocks, and how internal developers should handle new releases.
> Are you an internal developer? The following documents offer information about the different blocks, the Block Client APIs, the Store API, the templates and the testing process.
- [Blocks](internal-developers/blocks/README.md)
- [Stock Reservation during Checkout](internal-developers/blocks/stock-reservation.md)
- [Features Flags and Experimental interfaces](internal-developers/blocks/feature-flags-and-experimental-interfaces.md)
- [@woocommerce/extend-cart-checkout-block](https://www.npmjs.com/package/@woocommerce/extend-cart-checkout-block) This is a template to be used with @wordpress/create-block to create a WooCommerce Blocks extension starting point. It also showcases how to use some extensibility points, e.g. registering an inner block in the Checkout Block, applying filters to certain texts such as the place order button, using Slot/Fill and how to change the behaviour of the Store API.
