 ## Overview
 GraphQL is intended to be a replacement for REST APIs. [Read more](http://facebook.github.io/react/blog/2015/05/01/graphql-introduction.html) about rationale behind it.
 
+Example usage:
+```php
+$result = GraphQL::execute(
+  StarWarsSchema::build(),
+  'query HeroNameAndFriendsQuery {
+    hero {
+      id
+      name
+      friends {
+        name
+      }
+    }
+  }'
+)
+```
+
+Result returned:
+```php
+[
+  'hero' => [
+    'id' => '2001',
+    'name' => 'R2-D2',
+    'friends' => [
+      ['name' => 'Luke Skywalker'],
+      ['name' => 'Han Solo'],
+      ['name' => 'Leia Organa'],
+    ]
+  ]
+]
+```
+(see also [schema definition](https://github.com/webonyx/graphql-php/blob/master/tests/StarWarsSchema.php#L22) for type system of this example).

 This PHP implementation is a thin wrapper around your existing data layer and business logic. It doesn't dictate how these layers are implemented or which storage engines are used. Instead it provides tools for creating API for your existing app. These tools include:
 - Type system
 - Schema validation and introspection
