+Installation
+============
+
+Using `Composer <http://getcomposer.org/>`__
+--------------------------------------------
+
+To install this plugin, run ``composer require ker0x/cake_gcm`` or add this snippet in your project's ``composer.json``.
+
+.. code:: json
+
+    {
+        "require": {
+            "ker0x/cake_gcm": "~2.0"
+        }
+    }
+
+Enable plugin
+-------------
+
+You need to enable the plugin in your ``config/bootstrap.php`` file:
+
+.. code:: php
+
+    Plugin::load('ker0x/CakeGcm');
+
+If you are already using ``Plugin::loadAll();``, then this is not necessary.
+
+Use the component
+-----------------
+
+In ``src/Controller/AppController.php``, add :
+
+.. code:: php
+
+    $this->loadComponent('ker0x/CakeGcm.Gcm', [
+        'api' => [
+            'key' => '*****'
+        ]
+    ]);
+
+in your Controller's initialize() method. Replace ``****`` by your API Key.
+
+To get an API key, go to `<https://console.cloud.google.com/start>`.
+
+Then, in an action of one of your Controller, add the following code:
+
+.. code:: php
+
+    if ($this->Gcm->send($ids, $payload, $parameters)) {
+        // do some stuff
+    } else {
+        // do other stuff
+    }
+
+where:
+
+ - ``$ids`` is a string or an array of device ids. (required)
+ - ``$payload`` is an array containing the notification and/or some datas that will be passed to a device. (optional)
+ - ``$paramaters`` is an array of parameters for the notification. (optional)
+
+You could have the response of the request by using the function ``response()``:
+
+.. code:: php
+
+    $response = $this->Gcm->response();
