I created this project as a starting point for a Sinatra-based Ruby project hosted on Heroku. It's not the best setup (see the food inspections project for a better example) but it's enough to get going.
$ rvm install --default 2.1
$ gem install --no-ri mysql pg bundler heroku sass haml liquid
$ bundle install$ heroku create --stack cedar
$ git clone git@heroku.com:HEROKUPROJECTNAME.git .
$ heroku addons:add custom_domains:basic
$ heroku domains:add YOURDOMAIN
$ heroku domains:add www.YOURDOMAIN
