“This plugin is aimed at theme builders – both designers and developers,” Dwyer said in the announcement. “It is useful for sharing your designs between multiple sites or users. If you’re just building a site for yourself you probably don’t need it.”

I tested the plugin with the child theme option and it worked as expected. I was able to install it on another site with its unique name and template changes instantly applied. The export screen allows users to give the theme a name, description, and author information, which is saved to the new theme’s style.css file.

“At the moment the UI of this plugin is totally separate from Gutenberg,” Dwyer said. “In time we expect more integration with the Site Editor UI, to make it easier to access these features.

It would be helpful if the theme creation options allowed users to upload a unique screenshot that would be packaged with the theme download. I added this as an issue on the plugin’s GitHub repository, where anyone is welcome to contribute.

The Create Block Theme plugin makes designing and authoring a WordPress theme more approachable than ever before. It has the potential to rapidly increase the number of block themes available, if designers understand how to use it and submit their works to the Themes Directory. The Training Team is currently working on a course for Learn WordPress that will teach people how to create block themes using this plugin.

Create Block Theme was released under the WordPress.org plugins account and can be installed by searching for the plugin’s name in quotes.
