+A small-scale application that demonstrates how to use Flex Layout on the server. This site is not
+available publically, but can be run with the following command:
+
+`npm run universal:serve`
+
+**Note**: This server, unlike the demo-app, does **not** live reload. In order to incorporate build
+changes into the universal-app, it will need to be re-built/re-served each time.

+This entrypoint consolidates the logic for running Flex Layout on the server. Because it uses Node.js
+APIs, it must be segmented into the server bundle. This also helps avoid including server code in the
+browser bundle.
+
+The main export for this entrypoint, the `FlexLayoutServerModule`, can be imported into a server module
+file, e.g. `app.server.module.ts` as follows: 
+
+```typescript
+import {NgModule} from '@angular/core';
+import {FlexLayoutServerModule} from '@angular/flex-layout/server';
+
+@NgModule(({
+  imports: [
+    ... other imports here
+    FlexLayoutServerModule,
+  ]
+}))
+export class AppServerModule {}
+```
+
+This module, in addition to handling all of the style processing/rendering before the Angular app is
+bootstrapped on the server, also substitutes the version of `MatchMedia` with a server-compatible
+implementation called `ServerMatchMedia`.
