+
+## API Features
+
+### API Discovery
+
+To take full advantage of the client, load API definitions prior to use. To load an API:
+
+    urlshortener = client.discovered_api('urlshortener')
+
+Specific versions of the API can be loaded as well:
+
+    drive = client.discovered_api('drive', 'v2')
+
+Locally cached discovery documents may be used as well. To load an API from a local file:
+
+    doc = File.read('my-api.json')
+    my_api = client.register_discovery_document('myapi', 'v1', doc)
+
+### Authorization
+
+Most interactions with Google APIs require users to authorize applications via OAuth 2.0. The client library uses [Signet](https://github.com/google/signet) to handle most aspects of authorization. For additional details about Google's OAuth support, see [Google Developers](https://developers.google.com/accounts/docs/OAuth2). 
+
+Credentials can be managed at the connection level, as shown, or supplied on a per-request basis when calling `execute`.
+    
+For server-to-server interactions, like those between a web application and Google Cloud Storage, Prediction, or BigQuery APIs, use service accounts. Assertions for service accounts are made with `Google::APIClient::JWTAsserter`.
+
+    client = Google::APIClient.new
+    key = Google::APIClient::PKCS12.load_key('client.p12', 'notasecret')
+    service_account = Google::APIClient::JWTAsserter(
+        '123456-abcdef@developer.gserviceaccount.com',
+        'https://www.googleapis.com/auth/prediction',
+        key)
+    client.authorization = service_account.authorize
+
+### Batching Requests
+
+Some Google APIs support batching requests into a single HTTP request. Use `Google::APIClient::BatchRequest`
+to bundle multiple requests together.
+
+Example:
+
+    client = Google::APIClient.new
+    urlshortener = client.discovered_api('urlshortner')
+    
+    batch = Google::APIClient::BatchRequest.new do |result|
+        puts result.data
+    end
+    
+    batch.add(:api_method=>urlshortener.url.insert, 
+              :body_object => { 'longUrl' => 'http://example.com/foo' })
+    batch.add(:api_method=>urlshortener.url.insert, 
+              :body_object => { 'longUrl' => 'http://example.com/bar' })
+    client.execute(batch)
+    
+Blocks for handling responses can be specified either at the batch level or when adding an individual API call. For example:
+
+    batch.add(:api_method=>urlshortener.url.insert, :body_object => { 'longUrl' => 'http://example.com/bar' }) do |result|
+       puts result.data
+    end
+
+### Media Upload
+
+For APIs that support file uploads, use `Google::APIClient::UploadIO` to load the stream. Both multipart and resumable
+uploads can be used. For example, to upload a file to Google Drive using multipart
+
+    drive = client.discovered_api('drive', 'v2')
+   
+    media = Google::APIClient::UploadIO.new('mymovie.m4v', 'video/mp4')
+    metadata = {
+        'title' => 'My movie',
+        'description' => 'The best home movie ever made'
+    }
+    client.execute(:api_method => drive.files.insert,
+                   :parameters => { 'uploadType' => 'multipart' },
+                   :body_object => metadata,
+                   :media => media )
+   
+To use resumable uploads, change the `uploadType` parameter to `resumable`. To check the status of the upload
+and continue if necessary, check `result.resumable_upload`.
+
+    client.execute(:api_method => drive.files.insert,
+               :parameters => { 'uploadType' => 'resumable' },
+               :body_object => metadata,
+               :media => media )
+    upload = result.resumable_upload
+
+    # Resume if needed
+    if upload.resumable?
+        client.execute(upload)
+    end
+
