 ## 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:
+```php
+$result = GraphQL::execute(
+  StarWarsSchema::build(),
+  'query HeroNameAndFriendsQuery {
+    hero {
+      id
+      name
+      friends {
+        name
+      }
+    }
+  }'
+)
+```
+
+Result returned:
+```
+[
+  'hero' => [
+    'id' => '2001',
+    'name' => 'R2-D2',
+    'friends' => [
+      ['name' => 'Luke Skywalker'],
+      ['name' => 'Han Solo'],
+      ['name' => 'Leia Organa'],
+    ]
+  ]
+]

 - Type system
 - Schema validation and introspection
