title: How to add collaborators to a Firebase app?
body: <p>On the latest version of <code>Firebase</code> (Announced during Google I/O 2016), how do I add other people to my project or app whom I want to <code>collaborate</code> with? I came across IAM roles through <code>Settings &gt; Permissions</code>. Is this the right way? If I add person there and assign a role, say Editor, will he/she be notified about it through email? Will a request be sent or will they be added directly to that role?</p>
