 [Swagger](http://swagger.io) tooling for Rails API's. Generate beautiful API documentation, including a UI to explore and test operations, directly from your rspec integration tests.
 
-Rswag extends rspec-rails "request specs" with a Swagger-based DSL for describing and testing API operations. You describe your API operations with a succinct, intuitive syntax, and it automaticaly runs the tests. Once you have green tests, run a rake task to auto-generate corresponding Swagger files and expose them as JSON endpoints. Rswag also provides an embedded version of the awesome [swagger-ui](https://github.com/swagger-api/swagger-ui) that's powered by the exposed JSON. This toolchain makes it seamless to go from integration specs, which youre probably doing in some form already, to living documentation for your API consumers.
