+## What this section covers
+
+What one should expect when attempting to implement a server/client compliant
+with the Freechat protocol.
+
+## What this section does not cover
+
+Details on implementation are found under:
+
+* [JSON API Endpoints](#endpoints)
+
+Details what endpoints are available to send/receive data through.
+
+* [Structures](#structures)
+
+Details what kind of data is sent back and forth between clients and servers.
+
+## Overview Content 
+
+The Freechat protocol is based on HTTP and currently outlines a _json-based_ API
+hereafter referred to as just, the "JSON API". 
+Due to the standards already in place with HTTP and JSON it is safe to assume
+that this protocol be more of an outline for what HTTP endpoints to have and what kind of data is to be expected in exchanges.
+
+* Endpoints listed in the [JSON API Endpoints section](#endpoints).
+
+* Data structures are also outline under the [structures](#structures) section.
+
+Most servers will likely run on one of three ports, `80` for basic HTTP, `443` for secure HTTP traffic, or `4536` for most others.
+If using a _special port_ then servers should expect _user applications_ to specify the port.
+
+For connections over SSH or other protocols it really is up to server owners to let new users know about this important detail. 
+SSH based servers are not discouraged, in fact they are highly _encouraged_ to exist and operate :^)
