There is no release that can be installed with composer require shopware/development-bundle as the readme suggest.

If you clone the repo to custom/plugins the plugin:refresh command results in this:

Errors occurred while refreshing plugin list

[ERROR] The file "/var/www/html/custom/plugins/DevelopmentBundle/composer.json" is invalid. Errors:
