Spree is a complete open source commerce solution for Ruby on Rails. It was originally developed by Sean Schofield and is now maintained by a dedicated core team. You can find out more about by visiting the Spree e-commerce project page.
Spree actually consists of several different gems, each of which are maintained in a single repository and documented in a single set of online documentation. By requiring the Spree gem you automatically require all of the necessary dependency gems. Those gems are as follows:
All of the gems are designed to work together to provide a fully functional e-commerce platform. It is also possible, however, to use only the pieces you are interested in. So for example, you could use just the barebones spree_core gem and perhaps combine it with your own custom authorization scheme instead of using spree_auth.
Using the Gem
Start by adding the gem to your existing Rails 3.x application's Gemfile
Update your bundle
Then use the install generator to do the basic setup (add Spree to Gemfile, etc.)
rails g spree:site
Now its time to install all of the necessary migrations, assets, etc.
If you'd like to also install sample data and images you can follow up the above command with:
Now you just need to run the new migrations
rake db:migrate rake db:seed
If you also want some sample products, orders, etc. to play with you can run the appropriate rake task.

Working with the edge source (latest and greatest features)
The source code is essentially a collection of gems. Spree is meant to be run within the context of Rails application. You can easily create a sandbox application inside of your cloned source directory for testing purposes.
Clone the git repo
git clone git://github.com/railsdog/spree.git spree cd spree
Install the gem dependencies
Create a sandbox rails application for testing purposes (and automatically perform all necessary database setup)
Start the server
cd sandbox rails server
Each gem contains its own series of tests, and for each directory, you need to do a quick one-time creation of a test application and then you can use it to run the tests. For example, to run the tests for the core project.
rails new testapp -m spec/test_template.rb -T -J cd testapp rails g spree_core:install rake db:migrate db:seed db:test:prepare
Then run the tests
Note that each project has its own generator for "installing." This basically sets up the test app with what it needs to run (primarily migrations.) So for the spree_auth gem, for example, you would use the following
rails g spree_auth:install
Spree is an open source project. We encourage contributions. Please see the contributors guidelines before contributing.
The Github team has also been kind enough to write up some great documentation on working with pull requests. Contributions should be performed on topic branches in your personal forks - just issue your pull requests from there. We're also asking that you continue to log important issues for non-trivial patches in our lighthouse repository. You can just link the pull request in the ticket (and link the ticket in the pull request.)
