-#node-googleapis
+# google-api-nodejs-client [alpha]
 
-``node-googleapis`` allow you to generate client libs for [Google APIs](https://developers.google.com/apis-explorer/).
+`google-api-nodejs-client` is the Google's officially supported
+[node.js](http://nodejs.org/) client
+library for accessing Google APIs, it also supports authorization and
+authentication with OAuth 2.0.
 
+**Note**: This library is currently in *alpha* status, meaning that we can make
+changes in the future that *may not be compatible* with the previous versions.
+
 ## Installation
 
-    npm install googleapis
+The library is distributed on `npm`. In order to add it as a dependency,
+run the following command:
 
-## Usage
+    $ npm install googleapis
 
-    var googleapis = require('googleapis);
+## Guide
 
-    googleapis.load('urlshortener','v1', function(err, client) {
+Dynamically load any Google API and start making requests:
 
-      // set api key
-      client.setApiKey('AIzaSyAdjHPT5Pb7Nu56WJ_nlrMGOAgUAtKjiPM');
+    var googleapis = require('googleapis');
 
-      // batch requests
+    googleapis.load('urlshortener', 'v1', function(err, client) {
+      var params = { shortUrl: 'http://goo.gl/DdUKX' };
+      var request = client.urlshortener.url.get(params);
+      request.execute(function (err, response) {
+        console.log('Long url is', response.longUrl);
+      });
+    });
+
+Supported APIs are listed on
+[Google APIs Explorer](https://developers.google.com/apis-explorer).
+
+### API Clients
+
+Client libraries are generated during runtime by metadata provided by Google
+APIs Discovery Service. Metadata provided by Discovery Service is not cached,
+but requested each time you load a client. We're making changes to improve the
+situation for short-lived node processes. Below, there is an example of loading
+a client for [URL Shortener API](https://developers.google.com/url-shortener/).
+
+    googleapis.load('urlshortener', 'v1', function(err, client) {
+      if (!err) {
+        console.log('Client is loaded successfully');
+      }
+    });
+
+Alternatively, you may like to configure the client to append an API key to all
+requests you are going to make. Once you load a client library, you can set an
+API key:
+
+     googleapis.load('urlshortener', 'v1', function(err, client) {
+       client.withApiKey('YOUR API KEY HERE');
+       // make requestss
+     });
+
+To learn more about API keys, please see the [documentation](https://developers.google.com/console/help/#UsingKeys).
+
+### Requests
+
+Following sample loads a client for URL Shortener and retrieves the long url
+of the given short url:
+
+    googleapis.load('urlshortener', 'v1', function(err, client) {
+      // ...
       client
-        .newBatchRequest()
-        .add('urlshortener.url.get', { shortUrl: 'http://goo.gl/DdUKX' })
-        .add('urlshortener.url.insert', { longUrl: 'http://burcudogan.com' })
-        .execute(null, function(errs, results, headers){
-
+        .urlshortener
+        .url
+        .get({ shortUrl: 'http://goo.gl/DdUKX' })
+        .execute(function(err, result) {
+          // result.longUrl contains the long url.
         });
+    });
 
-      // a single request
+
+### Batch requests
+
+You can combine multiple requests in a single one by using batch requests.
+
+    googleapis.load('urlshortener', 'v1', function(err, client) {
+      // ...
+      var request1 =
+          client.urlshortener.url.get({ shortUrl: 'http://goo.gl/DdUKX' });
+      var request2 =
+          client.urlshortener.url.insert(null, { longUrl: 'http://goo.gl/A5492' });
+      // create from raw action name
+      var request3 = client.newRequest('urlshortener.url.list');
+
       client
-        .newRequest('urlshortener.url.get', { shortUrl1: 'http://goo.gl/DdUKX' })
-        .execute(null, function(err, result, headers){
+        .newBatchRequest()
+        .add(request1)
+        .add(request2)
+        .add(request3)
+        .execute(function(err, results) {
 
         });
+    });
 
-      // request builders
-      client.urlshortener.url
-        .get({ shortUrl: 'http://goo.gl/DdUKX' })
-        .execute();
+### Authorization and Authentication
+
+This client comes with an OAuth2 client allows you to retrieve an access token and
+refreshes the token and re-try the request seamlessly if token is expired. The
+basics of Google's OAuth 2.0 implementation is explained on
+[Google Authorization and Authentication
+documentation](https://developers.google.com/accounts/docs/OAuth2Login).
+
+A complete sample application that authorizes and authenticates with OAuth2.0
+client is available at `examples/ouath2.js`.
+
+#### Consent Page Url
+
+In order to ask for permissions from user to retrieve an access token, you
+should redirect them to a consent page. In order to create a consent page
+URL:
+
+    var googleapis = require('googleapis'),
+        OAuth2Client = googleapis.OAuth2Client;
+
+    var oauth2Client =
+        new OAuth2Client(CLIENT_ID, CLIENT_SECRET, REDIRECT_URL);
+
+    // generates a url allows offline access and asks permissions
+    // for Google+ scope.
+    var url = oauth2Client.generateAuthUrl({
+      access_type: 'offline',
+      scope: 'https://www.googleapis.com/auth/plus.me'
     });
 
+#### Retrieving Tokens
+Once user has given permissions on the consent page, Google will redirect
+the page to the redirect url you have provided with a code query parameter.
 
+    GET /oauthcallback?code={authorizationCode}
+
+With the code returned, you can ask for an access token as shown below:
+
+    oauth2Client.getToken(code, function(err, tokens) {
+      // contains an access_token and optionally a refresh_token.
+      // save them permanently.
+    });
+
+#### Making Authenticated Requests
+
+And you can start using oauth2Client to authorize and authenticate your
+requests to Google APIs with the retrieved tokens. If you provide a
+refresh_token, in cases when access_token is expired, it asks for a new
+access_token and replays the request.
+
+Following sample retrieves Google+ profile of the authenticated user.
+
+    oauth2Client.tokens = {
+      access_token = 'ACCESS TOKEN HERE',
+      refresh_token = 'REFRESH TOKEN HERE'
+    };
+
+    client
+      .plus.people.get({ userId: 'me' })
+      .withAuthClient(oauth2Client)
+      .execute(callback);
