This git repository provides a quickstart demonstrating how to use MongoHQ on OpenShift using Ruby 1.9.
Once you've created the quickstart, you'll need to create a MongoHQ account and add your authorization information to your Git repository. Making code changes will require you to set a public SSH key, and then to clone your new application Git repository onto your local machine. See the Getting Started page for more steps in this flow.
Easiest Quickstart ever! Just Deploy Now and go to your application URL to connect your OpenShift app to MongoHQ!
