When I try to add it to composer I get this:
Your requirements could not be resolved to an installable set of packages.
Problem 1 - The requested package phois/whois ~1.0 exists as phois/whois[dev-master] but these are rejected by your constraint.
I tried by adding "phois/whois": "~1.0" to require in my composer.json
@zachleigh Thanks for help!
