Adding/removing routes
$ git remote -v
$ git remote rm heroku
$ git remote add heroku get@heroku.com:takemystuff.git

Creating new route

If you have blown away your repo and you need to add your heroku remote instance back do this:

$ heroku create
$ git remote set-url heroku git@heroku.com:hidden-ridge-8790.git

This creates the heroku remote, and then points it to where you want

Pushing to heroku for first time

$ heroku create –stack cedar
$ git push heroku master
$ heroku run rake db:migrate

Mapping git remote back to an existing url

$ git remote add heroku git@heroku.com:hidden-ridge-8790.git

Misc commands

$ heroku run rake db:migrate (–app targetapp)
$ heroku logs (–app targetapp –tail)
$ heroku open
$ heroku run console
$ heroku domains:add academy.robotsandpencils.com
$ heroku info -a secret-waters-xxxx
