+[![Build Status](https://travis-ci.org/kevinschaich/gapi-client.svg?branch=master)](https://travis-ci.org/kevinschaich/gapi-client)
 
-A *very* thin Node wrapper for Google's client-side javascript V3 API.
+A *very* thin Node wrapper for Google's client-side javascript V3 API. For `gapi` documentation, see [Google API Client Reference](https://developers.google.com/api-client-library/javascript/reference/referencedocs) and for `API_KEY`, see [Google Developers Console](https://console.developers.google.com/).
 
-## Example
+## Install
 
 ```bash
 npm install --save gapi-client
 ```
 
-`index.js:`
+## Example
 
 ```javascript
-import gapi from 'gapi-client';
-
-//On load, called to load the auth2 library and API client library.
-gapi.load('client:auth2', initClient);
-
-// Initialize the API client library
-function initClient() {
-  gapi.client.init({
-    discoveryDocs: ["https://www.googleapis.com/discovery/v1/apis/drive/v3/rest"],
-    clientId: 'YOUR_CLIENT_ID',
-    scope: 'https://www.googleapis.com/auth/drive.metadata.readonly'
-  }).then(function () {
-    // do stuff with loaded APIs
-    console.log('it worked');
-  });
+import gapi from 'gapi-client'
+
+// Example : Auth2 (synchronous)
+const init = () => gapi.client.init(
+  discoveryDocs: ['https://www.googleapis.com/discovery/v1/apis/drive/v3/rest'],
+  clientId: 'YOUR_CLIENT_ID',
+  scope: 'https://www.googleapis.com/auth/drive.metadata.readonly'
+})
+
+gapi.load('client:auth2', init)
+
+// Example : Youtube (synchronous)
+const init = {
+  client: () => gapi.client.load('youtube', 'v3', init.youtube),
+  youtube: () => gapi.client.setApiKey('YOUR_API_KEY')
 }
 
+gapi.load('client', init.client)
+
+// Example : Youtube (promisified)
+new Promise(resolve => gapi.load('client', resolve))
+  .then(() => new Promise(resolve => gapi.client.load('youtube', 'v3', resolve)))
+  .then(() => gapi.client.setApiKey('YOUR_API_KEY'))
 ```
