+            <p>
+                HTTP messages are the foundation of web development. Web browsers and HTTP clients such as cURL create
+                HTTP request messages that are sent to a web server, which provides an HTTP response message.
+                Server-side code receives an HTTP request message, and returns an HTTP response message.

+            </h2>
+            <p>
+                Middleware is code that exists between the request and response, and which can take the incoming
+                request, perform actions based on it, and either complete the response or pass delegation on to the
+                next middleware in the queue. Your application is easily extended with custom middleware created by
+                yourself or <a href="https://packagist.org/search/?q=middleware" target="_blank">others</a>.

+                Expressive promotes and advocates the usage of Dependency Injection/Inversion of Control containers

+                However, Expressive does provide abstraction for templating, which allows you to write middleware that
+                is engine-agnostic.
