Rails 3: Heroku Herogit Plugin

I don't quite understand how to setup the herogit plugin recommended in the Heroku newsletter (https://github.com/jbarnette/herogit).

When I do $heroku config inside my app I already have the config info.

I also don't understand how to dep开发者_如何转开发loy on both apps using git push and heroku rake db:migrate.

Thanks

Herogit let's you store your Heroku credentials in your git repo so if you have apps which use different credentials, eg different clients then this makes it easier. If you're just dealing with the one app then there's not much point using it.
