+The `Predis\\Client` class
+--------------------------
+
+.. php:namespace:: Predis
+
+The `Client` class is the main class users interact with in Predis. The first
+thing you'll do to start communicating with Redis is instantiate a `Client`.
+
+Constructing a Client
+=====================
+
+The `Client` constructor takes two arguments. The first (``$parameters``) is a
+set of information about the Redis connection you'd like to make. The second
+(``$options``) is a set of options to configure the client.
+
+.. php:class:: Client
+
+   .. php:method:: __construct($parameters = null, $options = null)
+
+      Creates a new `Client` instance.
+
+      :param $parameters: Connection parameters
+      :param $options:    Client options
+
+
+Connection Parameters
+'''''''''''''''''''''
+
+These parameters are used to control the behaviour of the underlying connection
+to Redis. They can be specified using a URI string::
+
+   $client = new Predis\Client('tcp://127.0.0.1:6379?database=2')
+
+Or, using an associative array::
+
+   $client = new Predis\Client(array(
+       'scheme'   => 'tcp',
+       'host'     => '127.0.0.1',
+       'port'     => 6379,
+       'database' => 3
+   ));
+
+Client Options
