 2. Install Predis (included in this repository as a submodule) in the `/wp-content/predis` directory, since that's where the object cache expects it to reside.
 3. Add object-cache.php to the wp-content directory. It is a drop-in file, not a plugin, so it belongs in the wp-content directory, not the plugins directory.
 4. By default, the script will connect to Redis at 127.0.0.1:6379.

+### Connecting to Redis ###
+
+By default Predis uses `127.0.0.1` and `6379` as the default host and port when creating a new client
+instance without specifying any connection parameter:
+
+```php
+$redis = new Predis\Client();
+$redis->set('foo', 'bar');
+$value = $redis->get('foo');
+```
+
+It is possible to specify the various connection parameters using URI strings or named arrays:
+
+```php
+$redis = new Predis\Client('tcp://10.0.0.1:6379');
+
+// is equivalent to:
+
+$redis = new Predis\Client(array(
+    'scheme' => 'tcp',
+    'host'   => '10.0.0.1',
+    'port'   => 6379,
+));
+```
