How can 2 or more users develop for 1 heroku app?

I and one other person is developing a rail开发者_开发知识库s app.

Does heroku allow multiple users to manage a single app?

If not, is the only solution sharing a heroku account for 2 of us?

Add the second developer as a collaborator using either the web interface or the cli: http://devcenter.heroku.com/articles/sharing
