I want to install the extension "Improved Configurable Products for Magento 2" from Github.
Unfortunately it failed. Could someone give me a brief guide for the installation? I think it is one of the most important extensions for magento 2, and could help many people.
I already tried to add a registration.php and enabled + upgrade the module via comand line. But I think this is the wrong way?
I recommend to ask directly the extension's author: https://firebearstudio.com/contacts
