+Installation
+============
+
+The most easy way to install the library is via composer. To do so, you have to do
+the following:
+
+    php composer.phar require tedivm/fetch
+
+Composer will then ask you which version you want to install. Until there are stable
+versions, by using "@dev" it'll install the latest version.
+
+Sample Usage
+============
+
+This is just a simple code to show how to access messages by using Fetch. It uses Fetch
+own autoload, but it can (and should be, if applicable) replaced with the one generated
+by composer.
+
+    require 'autoload.php';
+
+    $server = new \Fetch\Server('imap.example.com', 993);
+    $server->setAuthentication('dummy', 'dummy');
+
+
+    $messages = $server->getMessages();
+    /** @var $message \Fetch\Message */
+    foreach ($messages as $message) {
+        echo "Subject: {$message->getSubject()}\nBody: {$message->getMessageBody()}\n";
+    }
