 This library is created in order to use reactPHP as a HTTP server for Slim framework. It will launch a Slim\App process when a request is made, and at the same time it will transfer data from reactPHP native objects into Slim objects. With this, we will be able to create a basic react server for a Slim framework application.

 ##Usage
 After the composer autoload requirement a Slim\App should be instanced and prepared as usual. Slim\App can be bootstrapped and all dependencies can be injected as you like, after that, a reactphp-slim server should be instanced and call the run method in it, using slim\App as parameter. The reactphp-slim server will act as intermediary and will launch the slim application through the ``process`` method when requested, this method avoids the usual request and response bootstrap made by Slim.
 
+When uploading files, move_uploaded_files() probably won't work, use native object methods to move the file.
