+MML is a set of HTML elements and attributes that can be used to describe 3D objects and experiences. The schema for these elements and attributes is defined in XML Schema Definition Language (XSD).
 
-These elements and attributes can be used without networking. However, when a HTML document including MML tags is run on a server and exposed via a websocket multiple users can interact with the same instance of the document at the same time.

 ## Networking (Networked DOM)
 MML is based on a set of libraries (built expressly for MML) called "Networked DOM".
 
+Networked DOM allows running a HTML document including script tags on a server and exposing it via a websocket which allows multiple users to interact with the same instance of the document at the same time.
+
 The server and network components necessary to support the multi-user mode are independent of the MML additions to HTML (and can be used with regular 2D HTML).
