If you don’t have rails or git, I recommend starting out by installing Homebrew. Here’s a nice guide to get your going.
Clone the repo
git clone git://github.com/NateW/obtvse.git
Install the bundle
cd obtvse
bundle install
Configure your settings
All the settings are inside config/config.yml. Be sure to set your admin username and password.
Push to Heroku
Heroku has a good getting started guide for pushing apps to their cedar stack (Rails 3 / ruby 1.9).
heroku create --stack cedar
Anytime you make changes, you can commit them and then push them to Heroku.
git add .
git commit -m "My changes here"
git push heroku master
Run database migrations and finish
heroku run rake db:migrate
heroku open
If you ever want to pull in the latest version of Obtvse just run this before you commit and push to heroku.
git pull github master
I did a quick run-through and got it running.
