+# @loopback/authorization
+
+A LoopBack 4 component for authorization support.
+
+**This is a reference implementation showing how to implement an authorization
+component, it is not production ready.**
+
+## Overview
+
+## Installation
+
+```shell
+npm install --save @loopback/authorization
+```
+
+## Basic use
+
+Start by decorating your controller methods with `@authorize` to require the
+request to be authorized.
+
+In this example, we make the user profile available via dependency injection
+using a key available from `@loopback/authorization` package.
+
+```ts
+import {inject} from '@loopback/context';
+import {authorize} from '@loopback/authorization';
+import {get} from '@loopback/rest';
+
+export class MyController {
+  @authorize({allow: ['ADMIN']})
+  @get('/number-of-views')
+  numOfViews(): number {
+    return 100;
+  }
+}
+```
