+`enchannel-zmq-backend` also gives access to all of the `channels` via a
+single multipled channel exposed via `createMainChannel`.
+
+```javascript
+import { createMainChannel } from 'enchannel-zmq-backend';

+Similar to the `createChannels` function, the `createMainChannel` function
+accepts both an identity and a runtime object.

+```javascript
+const channel = createMainChannel(identity, runtimeConfig);

+Messages that are sent via the mutliplexed channel need to define a `type`
+property that outlines which channel they should be sent under.
+
+```javascript
+const body = {
