 While this project does provide the means to *use* middleware implementations,

 As such, this project only bundles a few middleware implementations that are

+#### PSR-15 Middleware

+While we would love to support PSR-15 directly in `react/http` we choose a different path for middleware. One with 
+promises as expected return value, where the PSR-15 `MiddlewareInterface` and `RequestHandlerInterface` enforce 
+`ResponseInterface`. This isn't achievable with out on the fly changing of code, which is beyond the scope of this 
+package. However, our friends over at [Friends of ReactPHP](https://github.com/friends-of-reactphp) did came up with a 
+solution that makes using most PSR-15 middleware possible with `react/http` using the
