Thanks for reporting the bug with the Heroku installation instructions. I followed the instructions and found a problem with the "Deploy to Heroku" step. The instructions said to use "git push heroku". When I tried it I got the following message from Heroku:
08:32 [~/CSDL/heroku/wattdepot] $ git push heroku
Identity added: /Users/carletonmoore/.ssh/id_rsa (/Users/carletonmoore/.ssh/id_rsa)
Initializing repository, done.
No refs in common and none specified; doing nothing.
Perhaps you should specify a branch such as 'master'.
^CKilled by signal 2.
I had to Control C to break the connection.
I then ran the command "git push heroku master" and that worked. I've updated the installation guide.
Mahalo,
