I’ve just finished cataloguing 11 blocks which are now delivered by the WooCommerce plugin.
These blocks don’t appear to have much documentation, other than the release notes.
Most of the blocks are very similar. If you know how to use one you’ll know what to expect from another.
Blocks delivered by WooCommerce are originally developed in a separate plugin, called WooCommerce Blocks. For more information about which version of WooCommerce Blocks is bundled, and links to the release notes, see the WooCommerce plugin.
