Hello! In the last Dev Diary we mentioned that a user interface to install and update extensions, as well as flarum, was in the works. We have tagged a beta release for that extension and would love some feedback on it. Of course, as this is only a beta release please only install on a testing environment or if you really know what you are doing.
composer require flarum/package-manager:"@beta"
(We will most likely change the name of the extension)
