 ## About ##
 
-Predis is a flexible and feature-complete PHP client library for the Redis key-value 
-database. It currently comes in two flavors:
+Predis is a flexible and feature-complete PHP (>= 5.3) client library for the Redis key-value store.
 
- - the mainline client library, which targets PHP 5.3.x and leverages a lot of the 
-   features introduced in this new version of the PHP interpreter.
- - a backport to PHP 5.2.x for those who can not upgrade their environment yet 
-   (it admittedly has a lower priority compared to the mainline library, although we 
-   try to keep the two versions aligned as much as possible).

-Please refer to the TODO file to see which issues are still pending and what is due 
-to be implemented soon in Predis.
+For a version compatible with PHP 5.2 you must use the backported version of latest release in the 0.6.x series.

 ## Main features ##
 
 - Full support for Redis 2.0 and 2.2. Different versions of Redis are supported via server profiles.
 - Client-side sharding (support for consistent hashing and custom distribution strategies).
-- Command pipelining on single and multiple connections (transparent).
+- Command pipelining on single and multiple connections.
 - Abstraction for Redis transactions (>= 2.0) with support for CAS operations (>= 2.2).
 - Lazy connections (connections to Redis instances are only established just in time).
 - Flexible system to define and register your own set of commands to a client instance.

+### Loading Predis
+
+Predis relies on the autoloading features of PHP and complies with the 
+(PSR-0 standard)[http://groups.google.com/group/php-standards/web/psr-0-final-proposal] 
+for interoperability with the major frameworks and libraries.
+
+When used in simple projects or scripts you might need to define an autoloader function:
+
+spl_autoload_register(function($class) {
+    $file = PREDIS_BASE_PATH . strtr($class, '\\', '/') . '.php';
+    if (file_exists($file)) {
