-         <p>As a platform N2O provides a set of techniques applicable and useful
-            for ML languages and Erlang, but it seems that N2O discipline is helpful
-            in other programming languages too. As an enterprise protocol federation
-            N2O provides solid XMPP/WS/CORBA replacement, defining the following
-            services that could run in a distributed environment: business process
-            management, distributed data storage, application framework,
-            publish/subscribe broker, messaging and mail services, etc.</p>

-        <h3>N2O as an Application Server</h3>
-
-         <p>N2O.DEV is an Erlang N2O implementation of application services
-            run inside Erlang virtual machine. Each service implemented as
-            protocol module that can be injected to N2O accept looper.
-            Developing application for N2O means writing your application
-            protocol modules that handle pure logic.</p>
-
-        <p> As Erlang/OTP application N2O is an embeddable message protocol
-            loop library for WebSocket, MQTT, and TCP servers, it provides
-            basic features, such as process management; virtual nodes ring
-            for request processing; session, encoding, MQ, cache and log services.</p>
-        <p>
-            The main two usages of N2O:
-            1) live in client connection processes of server; 2) live in server workers
-            and handle all requests from client processes. You can add you own feature-set
-            versions of N2O with different Github repositories. N2O is distributed by modules
-            not as monolith application, so you can pick and pack different feature combinations.

-        <h3>N2O as a Web Framework</h3>
-
-<p>Web logic should be as much declarative as possible.
-   The language should be readable by Java, .NET engineers.
-   NITRO protocol is what we called Web Framework inside N2O ecosystem.
-   If you plug the NITRO module, you automatically enable web framework for all devices.
-   It resembles Nitrogen API, well known Erlang Web Framework.
