+# Angular Universal Socket Engine
+
+Framework and Platform agnostic Angular Universal rendering.
+
+## Usage Server
+
+`npm install @nguniversal/socket-engine @nguniversal/common --save`
+
+```js
+const socketEngine = require('@nguniversal/socket-engine');
+
+// * NOTE :: leave this as require() since this file is built Dynamically from webpack
+const {AppServerModuleNgFactory, LAZY_MODULE_MAP} = require('./dist/server/main');
+
+socketEngine.startSocketEngine(AppServerModuleNgFactory);
+```
+This will the socket engine which internally hosts a TCP Socket server.  
+The default port is `9090` and host of `localhost`
+You may want to leave this as a plain `.js` file since it is so simple and to make deploying it easier, but it can be easily transpiled from Typescript.  
+
+## Usage Client
+
+Your client can be whatever language, framework or platform you like.  
+As long as it can connect to a TCP Socket (which all frameworks can) then you're good to go.
+
+This example will use JS for simplicity
+```typescript
+import * as net from 'net';
+
+const client = net.createConnection(9090, 'localhost', () => {
+  console.log('connected to SSR server');
+});
+
+client.on('data', data => {
+  const res = JSON.parse(data.toString()) as SocketEngineResponse;
+  expect(res.id).toEqual(1);
+  expect(res.html).toEqual(template);
+  server.close();
+  done();
+});
+
+const renderOptions = {id: 1, url: '/path', document: '<app-root></app-root>'} as SocketEngineRenderOptions;
+client.write(JSON.stringify(renderOptions));
+```
