 ## Running the tests
 
-After installing dependencies with `bundle install`, you can run the unit tests with `rake test:units` and the remote tests with `rake test:remote`. The unit tests mock out requests and responses so that everything runs locally, while the remote tests actually hit the carrier servers. For the remote tests, you'll need valid test credentials for any carriers' tests you want to run. The credentials should go in ~/.active_shipping/credentials.yml, and the format of that file can be seen in the included [credentials.yml](https://github.com/Shopify/active_shipping/blob/master/test/credentials.yml).

 ## Development
 
 Yes, please! Take a look at the tests and the implementation of the Carrier class to see how the basics work. At some point soon there will be a carrier template generator along the lines of the gateway generator included in Active Merchant, but carrier.rb outlines most of what's necessary. The other main classes that would be good to familiarize yourself with are Location, Package, and Response.
