The Shoppe code repositories
We have two main repositories which may be of interest to you. As Shoppe itself is just an engine, it has it's own repository which can be included into any Rails application through a RubyGem. Additionally, we also have a full Rails application (our demo store) which can be used as a basis for any new store if you don't wish to start from scratch.
The core repository
The core repository contains all the Shoppe models, admin UI and logic needed to run your store. Unless your contributing to the core project, you won't need make any changes to this. This repository is packed up as a RubyGem
The example/demo site
The example/demo Rails application provides a fully working, fully integrated, Shoppe store which can be used as the basis for a new application.
