+HTTP Signatures Guzzle 3
+===
+
+Adds Guzzle 3 support to [99designs/http-signatures][99signatures]
+
+Signing with Guzzle 3
+---
+
+This library includes support for automatically signing Guzzle requests using an event subscriber.
+
+```php
+use HttpSignatures\Guzzle\CreateRequestSubscriber;
+
+$client = new \Guzzle\Http\Client('http://example.org');
+$client->addSubscriber(new CreateRequestSubscriber($context));
+
+// The below will now send a signed request to: http://example.org/path?query=123
+$client->get('/path?query=123', array(
+  'Date' => 'Wed, 30 Jul 2014 16:40:19 -0700',
+  'Accept' => 'llamas',
+))->send();
+```
