Unable to install with composer

[megawubs]

Hi, I'm exited to try this out! But when following the docs, I'm unable to run composer global require makalin/php-universe and got this error:

Could not find a matching version of package makalin/php-universe. Check the package spelling, your version constraint and that the package is available in a stability which matches your minimum-stability (stable).   

Also, searching packagist for makalin/php-universe does not yield any resuls

Have you published the packages? I would love to play with this and see what it is capable of.
