-Predis is a flexible and feature-complete PHP (>= 5.3) client library for [Redis](http://redis.io).
+Predis is a flexible and feature-complete [Redis](http://redis.io) client library for PHP >= 5.3 and
+[HHVM](http://www.hhvm.com) >= 2.3.0.
 
 Predis does not require any additional extension loaded in PHP but can be optionally paired with the
 [phpiredis](https://github.com/nrk/phpiredis) C-based extension to lower the overhead of serializing
 and parsing the Redis protocol. An asynchronous implementation of the client, albeit experimental,
 is also available through [Predis\Async](https://github.com/nrk/predis-async).
 
-The library can also be used with [HHVM](http://www.hhvm.com) >= 2.3.0 although we cannot guarantee
-that you will not run into unexpected issues especially in some obscure corner cases, mostly due to
-the fact that HHVM is still being actively developed and not 100% compatible with PHP.
+While it can be used with HHVM, there are no guarantees that you will not run into unexpected issues
+especially in some obscure corner cases due to the fact that HHVM is still under heavy development
+and not yet 100% compatible with PHP.
