+**Looking for the next version of the OpenAPI Specification?  [See here](https://github.com/OAI/OpenAPI-Specification/tree/OpenAPI.next).**
+
 The goal of The OpenAPI Specification is to define a standard, language-agnostic interface to REST APIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code, documentation, or through network traffic inspection.  When properly defined via OpenAPI, a consumer can understand and interact with the remote service with a minimal amount of implementation logic.  Similar to what interfaces have done for lower-level programming, OpenAPI removes the guesswork in calling the service.
 
 Use cases for machine-readable API interfaces include interactive documentation, code generation for documentation, client, and server, as well as automated test cases.  OpenAPI-enabled APIs expose JSON files that correctly adhere to the OpenAPI Specification, documented in this repository.  These files can either be produced and served statically, or be generated dynamically from your application.
