In order to use Roomkey, you'll have to download the application first on your phone, tablet, or computer. All of Roomkey's capabilities live inside the application, so it's necessary that you download it.
Once inside the app, you'll be prompted to log in or sign up. You'll need to create an account in order to use Roomkey. When you've got your account set up, you can begin to use Roomkey, create or join rooms, customise your avatar to look just like you, and invite your friends or colleagues to meet, chat, or just hang out.
