 # PSR-7 and PSR-15 JWT Authentication Middleware
 
 This middleware implements JSON Web Token Authentication. It was originally developed for Slim but can be used with any framework using PSR-7 and PSR-15 style middlewares. It has been tested with [Slim Framework](http://www.slimframework.com/) and [Zend Expressive](https://zendframework.github.io/zend-expressive/).
