Heroku deploy instructions out of date?

[jonsmithers]

Instructions say to run ./deploy.sh <app-name>, but there is no deploy.sh file in this repo. So, I tried running bash deploy-heroku.sh instead. But it seems like that script cd's to incorrect working directory, resulting in a "no such file" type error. So I tried manually running the individual commands in the deploy script, but I ended up with this error in heroku:

App not compatible with buildpack: https://github.com/heroku/heroku-buildpack-ruby.git#v227

I think I just made a duplicate of #225
