 You need :
 
- - the [erldis binaries](http://github.com/cstar/erldis/tree/binaries) branch available in your Riak installation.
+ - [credis](http://code.google.com/p/credis/). compile (`make`)
+
+ - [erlang_credis](http://github.com/videlalvaro/erlang_credis). compile (`make`)
+
+ You have to specify the path to your credis installation.
 
  - [Redis](http://code.google.com/p/redis/) (Any version will do). 
 
  - [Riak](http://riak.basho.com/)
 
- - compile (`erlc riak_redis_backend.erl`) and copy the beam file in your riak installation.
+ - compile (`erlc riak_redis_backend.erl`)
 
 Configure riak :
 
-  `{storage_backend, riak_dets_backend}` in the `etc/app.config`
+In `etc/app.config` change the option storage_backend to:
+
+  `{storage_backend, riak_redis_backend}`
+
+And add the paths to the driver and the backedn so riak can find them:
+
+  '{add_paths, ["/path/to/riak_redis_backend", "/path/to/erlang_credis/ebin"]}'
 
 For the time being, Redis must run locally. I will certainly add the line to configure the redis host and port.
